Digital Isolation for Safety and Reliability in Industrial Power SuppliesJ U L Y 2 0 1 9
Galvanic isolation means “no current flow”
OUT signal faithfully represents IN signal
Data passes through like it was “0 impedance”
Input to output side is actually high impedance
Net result:
Input signal is transferred to output
No current flow between GND1 and GND 2

Why Isolate?
Traditional Isolation - Optical Coupling
Poor reliability
Key parameters drift over temperature, VDD and age
Poor timing characteristics
Long delay times slow system throughput
Key parameters (e.g. jitter) often not specified
Poor noise immunity (CMTI)
Fast common mode transients can corrupt data
Additional components required to meet CMTI specs
Energy inefficient
Requires high current to ensure good performance
Modern Isolation – CMOS Based Capacitive Coupling
High reliability
Inherent stability over temperature, VDD and age
CMOS isolator reliability is 10x that of optocouplers
Excellent timing characteristics
Low propagation delay and channel skew
Excellent part to part matching
High noise immunity (CMTI)
High performance digital isolators achieve 200 kV/µs
2x improvement over other products available today
Low power
Efficient isolators require a fraction of an optocoupler’s power

Definitions Isolation Rated Voltage (1 minute rating) Maximum voltage an isolation barrier is independently
qualified to with-stand for 1 continuous minute; typically 2.5kVrms, 5kVrms
Working Voltage (life time) Highest possible RMS value of an ac/dc voltage across
insulation barrier when device operated at rated voltage
Creepage Distance along the insulating surface an arc may travel.
Clearance Shortest path through air that an arc may travel.
Functional Insulation Insulation required for a product to function
Provides no protection against electrical shock
Basic insulation Insulation that provides single-level protection against shock.
Reinforced/Double Insulation Insulation that provides two-levels of protection against electric
shock
