Features

• General

– 16 bit ST-SPI for full and diagnostic

– Programmable BULB/LED mode

– Integrated PWM and phase shift generation

unit

– 160 Hz internal PWM fallback frequency

– Advanced limp home functionalities for

robust fail-safe system

– Very low standby current

– Optimized electromagnetic emissions

• Diagnostic

– Multiplex proportional load current sense

– Synchronous diagnostic of overload and

short to GND, output shorted to VCC,

ON-state and OFF-state open-load

– Programmable case overtemperature

warning

• Protections

– Load current limitation

– Self limiting of fast thermal transients

– Power limitation and overtemperature

shutdown (latching off or autorestart)

– Undervoltage shutdown

– Overvoltage clamp

– Reverse battery protected through power

outputs self turn-on (no external

components)

– Load dump protected

– Protection against loss of ground
