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
