? General

– Dual channel with 24-bit ST-SPI for full diagnostic and digital current

sense feedback

– Integrated 10-bit ADC for digital current sense

– Integrated PWM engine with independent phase shift and frequency

generation (for each channel)

– Programmable Bulb/LED mode for all channels

– Advanced limp-home functions for robust fail-safe system

– Very low standby current

– Optimized electromagnetic emissions

– Very low electromagnetic susceptibility

– Control through direct inputs and/or SPI

– Compliant with European directive 2002/95/EC

– Capacitive loads charging mode

? Diagnostic functions

– Digital proportional load current sense

– Synchronous diagnostic of overload, short to GND and harness

protection

– Asynchronous diagnostic of output shorted to VCC and OFF-state openload

– Built In Self-Test for ADC and harness protection

– Programmable case overtemperature warning

? Protections

– Full configurable wire harness protection (STi2Fuse)

– Load current limitation

– Self-limiting of fast thermal transients

– Latch-off or programmable time limited auto restart (power limitation and

overtemperature shutdown)

– Undervoltage shutdown

– Overvoltage clamp

– Load dump protected

– Protection against loss of ground
