WARNING When testing this system with lithium-ion (Li-Ion) batteries, take care not to overcharge or overdischarge the batteries, or to sink/source more than the maximum current recommended by the manufacturer of the battery. Exceeding these ratings can not only damage the battery, but can also cause it to explode or catch on fire.
GENERAL DESCRIPTION The AD8452 system demo evaluation kit is a recommended starting point for users building battery formation and test equipment based on the Analog Devices, Inc., AD8452 precision analog front end and pulse-width modulation (PWM) controller. The evaluation kit includes an analog interface board and a power module board.
In addition to the AD8452, the analog interface board also includes an AD5689R 16-bit, precision digital-to-analog converter (DAC) to set the current and voltage set points, and an AD7173-8 24-bit, Σ-Δ analog-to-digital converter (ADC) to monitor the battery voltage and current.
The analog interface board includes built-in voltage regulators so that it can be powered either from the bus power inputs or directly from a 15 V dc supply through a screw terminal connector.
The analog interface board connects to the Analog Devices System Demonstration Platform (SDP-S) through a 120-pin connector. The SDP-S board connects to the user interface software through the USB port, allowing the user to set the current and voltage set point as well as the mode of operation (charge or discharge). In addition, the user can monitor the battery voltage and current by reading the data output from the AD7173-8.
The analog interface board connects to the power module board through three multipin headers. This modular approach allows the user to design and test their own power module boards, designed for the current output range in their end applications, with the analog interface board of this reference design.
The standard power module board supports charge and discharge currents of up to 10 A. It includes the power metal-oxide semiconductor field effect transistors (MOSFETs), the inductor, and the input and output capacitors required to implement a buck or boost regulator, depending on the operating mode.
Full specifications of the AD8452 are available in the product data sheet, which must be consulted in conjunction with this user guide when working with the evaluation kit.

EVALUATION BOARD HARDWARE SETTING UP THE EVALUATION SYSTEM Figure 25 to Figure 27 show the analog interface board schematics, and Figure 17 shows the power module board schematic.
The analog interface board includes the AD8452 (U7), the AD7173-8 24-bit Σ-Δ ADC (U10), and the AD5689R 16-bit DAC (U6).
Connector J1, Connector J2, and Connector J3 mate with the power module board to provide the PWM control signals for the MOSFET drivers, as well as the battery voltage, the current signals, and the supply voltage for the analog interface board. The modular approach of the system allows users to use the analog interface board with their custom design power module. Table 1, Table 2, and Table 3 list the header pin names and functionalities.
The power module board includes an ADuM7223 MOSFET driver (U1), a high-side and low-side power MOSFET, switching inductor, and input output capacitors.
Connect the boards as shown in Figure 1.
POWERING THE SYSTEM The evaluation system requires power from an external dc power source. The main power input is connected through the banana terminals labeled J4 and J5 on the analog interface board. The input voltage to the system can be between a 10 V minimum and a 30 V maximum, depending on the operating voltage of the power module board. The standard power module board, included in this system, allows operation up to 20 V. The input current depends on the desired load current (that is, battery charge current). To run the board at the rated 10 A charge current into a 5 V load, the input 12 V power supply must be capable of delivering at least 5 A.
The analog interface board can be powered from the main power input or from a separate dc supply using the J6 screw terminal connector. In the default configuration, the analog interface is powered from the main power input terminals. To power the analog interface board from an independent 15 V source, remove Resistor R4 and populate a 0 Ω jumper at R1.
To turn on the board, apply 12 V input power of the correct polarity between terminals J4 and J5. The light emitting diodes (LEDs) on the lower left of the analog interface board illuminate, indicating the analog interface voltage regulators are operating.
The battery or electronic load can be connected to the banana terminals labeled J8 and J9.
AD8452 COMPENSATION NETWORKS The evaluation system ships configured for connection to a Chroma 63600 series electronic load. If the electronic load of the user has a different response, or if the user wants to use the system with a rechargeable battery, adjust the compensation values in each of the four AD8452 control loops to ensure system stability. The online AD8450/AD8451 compensator design tool at http://analogplayground.com/AD8450 can be used to assist with compensation by adding the current limit shunt resistance to the inductor equivalent series resistance (ESR) and entering the sum in the RL Inductor ESR (Ω) entry box. See the AN-1319 for detailed analysis of the compensation.
SERIAL INTERFACE The evaluation system uses the serial peripheral interface (SPI) on the SDP-S board to read the current and voltage ADCs, and to set the current and voltage set points with the AD5689R DAC.

POWER MODULE BOARD DESCRIPTION Figure 17 shows the power module board schematic. The input bus supply connects to the power module board through the J1 connector. MOSFET Q1 is used to connect or disconnect the input power bus to the switching power section if the input is within the operating voltage range.
The power module includes input capacitors, a low-side and high-side MOSFET, an inductor, and output capacitors. Depending on the mode of operation, the AD8452 drives the power module in either step-down (buck) or step-up (boost) mode. The AD8452 drives the power module in synchronous mode for improved efficiency. A current sense resistor (R14) is connected in series with the inductor to provide inductor current feedback to the AD8452 to prevent reverse current.
The ADuM7223 translates the 5 V level PWM signals from the AD8452 into low impedance, 10 V drive signals for the MOSFETs. A simple linear regulator circuit on the analog interface board generates the 10 V rail for the MOSFET driver from the main input rail.
The power module board includes a 3 mΩ sense resistor (R16) for measuring the output current. The output of the power module board connects to the analog interface board through Connector J3.
ANALOG INTERFACE BOARD DESCRIPTION The analog interface board includes the AD8452 as well as an AD5689R DAC to configure the set points and an AD7173-8 ADC to monitor the current and voltage.
The analog interface board includes an ADP1612 single-ended primary inductor converter (SEPIC) to provide a wide input voltage range followed by a pair of ADP7102 linear regulators to generate 12 V and 5 V, and an ADM8829 switched capacitor inverter that generates −5 V for the AD8452 so that it can measure and output voltages close to 0 V.
The current sense programmable gain instrumentation amplifier (PGIA) of the AD8452 has a fixed gain of 66. With a gain of 66, a 10 A output current results in an output voltage of 1.98 V at TP6 (Pin ISMEA).
The voltage sense programmable gain difference amplifier (PGDA) has a fixed gain of 0.4. With a gain of 0.4, a 4 V battery voltage results in a 1.6 V output at TP13 (Pin BVMEA).
The AD7173-8 ADC measures the voltage and current signals and reports the values to the user interface software through the SDP-S interface. The default full-scale input range of the AD7173-8 is configured at 2.5 V. The AD5689R DAC Output A configures the constant current set point, and Output B sets the constant voltage set point. The default DAC output range is also from 0 V to 2.5 V. Given the current and voltage gain settings of the AD8452, the current and voltage set points can be calculated as follows:
PGIA_GAIN = 66
PGDA_GAIN = 0.4
Constant_Current_Setpoint = VDAC_A/(PGIA_GAIN × 0.003)
Constant_Current_Setpoint = VDAC_B/(PGDA_GAIN)
The ADCMP370 comparator at U11 controls the transition from nonsynchronous to synchronous switching. When the output current is less than 1 A, the comparator clamps the SS pin to less than 4.5 V and forces the AD8452 to operate in nonsynchronous switching mode. When the output current exceeds 1 A, the SS pin is allowed to rise above 4.5 V, and the AD8452 transitions to synchronous switching mode. Operating in nonsynchronous switching mode at low output currents effectively eliminates reverse current though the inductor. At higher currents, synchronous switching provides improved converter efficiency.
The Q8, Q9, Q10, and Q11 output transistors form a bidirectional load switch on the output of the dc-to-dc converter. The load switch is disabled by default with a shorting jumper across JP1. Removing the shorting jumper across JP1 enables the load switch and demonstrates how the load switch can control current direction during low current operation.
The state of the load switch FETs is determined by the operating mode and the output current. When the ADCMP370 at U17 detects that the output current is less than 500 mA, the mode signal enables one pair of load switch FETs and disables the second pair of load switch FETs. Current is forced through the diode in parallel with the disabled FET pair, controlling the direction of current flow. Additionally, the increased output impedance of the diode allows enhanced current control when operating below 500 mA. When the output current exceeds 500 mA, both pairs of load switch FETs are enabled, providing a low resistance current path and maximum power efficiency.

SOFTWARE OPERATION When the software launches, the window shown in Figure 14 opens and the software starts communicating with the analog interface board. The software starts with the power module disabled, which allows the user to configure the set points before any current flows into the load.
DESCRIPTION OF THE MAIN WINDOW The main window shows the system status at a glance. The system diagram quickly shows whether the system is set to either charge mode or discharge mode, and the digital indicators next to the battery icon and the current icon show the readings for battery voltage and current.
The POWER STAGE OFF button indicates that the system is disabled. Clicking this button enables the power module (and the text changes to POWER STAGE ON). Similarly, the MODE: CHARGE button indicates that the system is currently in charge mode. Clicking this button changes the power module configuration (and the text changes to MODE: DISCHARGE).
The Amp-Hours indicator is a simple integrator. It takes the battery current measurement every 100 ms, calculates the equivalent amp-hour value, and accumulates the result with the previous result. This calculation allows the system to measure battery capacity from the time the battery is enabled until it is fully charged or discharged, or until the mode setting is changed.
To change the constant current or constant voltage set point values, type the new value into the corresponding field, in units of amps or volts, respectively, and press the Enter key.
The time data chart shows a strip chart of current and voltage while the battery charges or discharges.
Figure 15 shows the main window in constant current, discharge mode.

CONFIGURATION TAB Click Configure System to open the configuration tab. This tab contains several options described in the following sections.
Sample Timing Controls
Sample Interval sets the rate at which the system updates the battery voltage and current measurements. The sample interval is the rate at which the screen updates, and is completely independent of the analog control loop.
Graphing Sampling Rate Multiple sets the update rate for the main window as a ratio of the sample interval. For example, setting the Sample Interval to 1 sec and the Graphing Sample Rate Multiple to 1 results in chart updates every second. Setting the Graphing Sampling Rate Multiple to 5 results in graph updates only every 5 sec.
Calibration Controls
The gain correction and offset controls allow the user to perform system level calibration. The measurements displayed in the main window are the nominal output from the ADC scaled with the following equation:
Output Measurement = (Nominally Scaled Measurement − Offset Correction) × Gain Correction
where Nominally Scaled Measurement uses the typical values for the sense resistor, the ADC reference, the AD8452 gain, and so on.
Current Gain Correction is the gain correction constant for the current measurement. The default is 1.
Current Offset (A) is the offset correction constant for the current channel, in units of amps. The default is 0.
Voltage Gain Correction is the gain correction constant for the voltage measurement. The default is 1.
Voltage Offset (V) is the offset correction constant for the voltage channel, in units of volts. The default is 0.
Hardware Configuration Controls
As indicated in the main window, the hardware configuration controls must reflect the actual configuration of the power module and analog interface boards. If there is a mismatch between the settings in these controls and the actual hardware configuration, excessive current can be sourced into (or sunk from) the battery.
ADC Range (V) is the nominal ADC input range, with a default of 2.5 V.
DAC Range (V) is the nominal DAC output range, with a default of 2.5 V.
Sense Resistor (Ohms) is the nominal value of the sense resistor on the power module board. The default is 0.003 Ω (3 mΩ).
Current Sense Gain is the gain setting for the AD8452 programmable gain current sense instrumentation amplifier. The default value is 66.
Voltage Sense Gain is the gain setting for the AD8452 programmable gain differential voltage sense amplifier. The default is 0.4.
Full Scale Current is the setting to change the scaling of the current setpoint range. This value matches the full-scale current of the power module.
Clicking Reset Ahr Meter resets the amp-hour counter in the main window to 0.

TROUBLESHOOTING SOFTWARE To troubleshoot the software, take the following steps:
1. Always install the software prior to connecting thehardware to the PC.
2. Always allow the install to fully complete (the software is atwo part install: the ADC software and the SDP drivers).Completing the install may require a PC restart.
3. When you first plug in the SDP-S board via the USB cableprovided, allow the new Found Hardware Wizard to run.This step may take a little time; however, the wizard mustrun to completion prior to starting the software.
4. When the board does not appear to be functioning, ensurethat the ADC evaluation board is connected to the SDP-Sboard and that the board is being recognized in the DeviceManager, as shown in Figure 11.
HARDWARE To troubleshoot the hardware, take the following steps:
1. If the software does not read any data back, check that thepower is applied within the power ranges described in thePowering the System section.
2. Using a voltmeter, verify the following voltages on theanalog interface board:
• 10.5 V ±3% at TP1• 12 V at TP2• 5 V at TP4• −5 V at TP5
3. Launch the software and read the data. If nothing happens,exit the software.
4. Power down the board and relaunch the software.5. If no data is read back, confirm that the power module
board is plugged into the analog interface board, and thatthe analog interface board is connected to the SDP-S boardand that the board is being recognized in the DeviceManager, as shown in Figure 11.
