Release Note: Revision bars indicate significant changes to the previous document.

1. General Information

This Application Note shall guide the customer through the transition of the obsoleteHall sensors HAL 805, HAL 810 and HAL 815 to the new family members HAL 830 andHAL 835. The HAL 805 and the HAL 815 can be replaced by HAL 830 or HAL 835. TheHAL 810 can be replaced by HAL 835.

1.1. Certification

TDK-Micronas GmbH fulfills the requirements of the international automotive standardISO/TS 16949 and is certified according to ISO 9001:2000. This ISO standard is aworldwide accepted quality standard.

1.2. Support

We advise you to register on https://service.micronas.com in order to obtain access tothe workgroups for our various product families. Here you are able to get support byopening a support ticket in the customer support system. Additionally, once registered,you will receive notifications on software and Application Notes updates.

2. Specific Transition Recommendation: HAL 805/HAL 815 HAL 830

2.1. Block Diagram and Digital Signal Processing

Block Diagram

The major change is the implementation of the Open-Circuit Detection block. Pleasecheck section “Open-Circuit Detection” of the HAL 83x data sheet.

Fig. 2–1: Block diagram (HAL 805/HAL 815 on the left side; HAL 830 on the right side)

Digital Signal Processing

The HAL 830 has an improved access to the ADC-Readout register, which is now inde-pendent of the EEPROM settings.

The differences of the registers are marked in red.

Fig. 2–2: Digital signal processing (HAL 805/HAL 815 on the left side; HAL 830 on the right side)



2.2. Differences in the EEPROM Content

Red: changed registers

Green: new registers

Register

Registers for HAL 830 have been modified. In addition the GP registers and a D/A Readout register were added.

GP register No Yes



2.4. Software / Hardware

Software

The programming and calibration methods are identical for all HAL 8xy family members.

The main difference is that the software for HAL 805/815 is only based on Visual Basic®

and the HAL 83x programming software is based on LabVIEWTM and on Visual Basic.

General View

In the general view of both software versions all programmable registers can be read orwritten.

Fig. 2–3: Programming software - Visual Basic based

Fig. 2–4: HAL 83x Programming software (general tab)- LabVIEW based



Calibration

In the former Visual Basic software the calibration procedure is done in a separate win-dow which opens when the user clicks on the menu “Calibrate”.

In the LabVIEW version all actions are done in the same window. To get to the calibra-tion procedure the user has to click on the tab “2-point calibration sequential”.

Fig. 2–8: 3-point calibration sequential - LabView based



Fig. 2–9: 2-point calibration parallel - Visual Basic based

Fig. 2–10:2-point calibration parallel - LabVIEW based

Hardware

Just as for HAL805 and HAL815, the required hardware to program the HAL 830 is stillTDK-Micronas’ HAL Programmer V5.1.
