Automotive High-Voltage Interlock Reference Design(TIDA-01445)

This reference design is a low BOM design that has good coverage of automotive interlock connection diagnosis. In hybrid or electric vehicles (HEV/EVs), battery management systems, traction inverters, DCDC converters, onboard chargers, and other subsystems that operate at high voltages need to have interlock. Interlock is a current and voltage loop mechanism used to detect tampering or opening of the high-voltage equipment or service disconnect switch.This design covers generating and monitoring mechanism of high voltage interlock system.

Возможности
