Features

• AEC-Q100 qualified

• Full ISO26262 compliant, ASIL-B systems ready

• General

– Eight LS drivers

– 16-bit SPI interface for outputs control and for diagnosis data

communication

– Daisy chain compatible and available even with 8-bit SPI

– 2 parallel input pins with input mapping functionality

– Cranking capability down to VBATT = 3 V

– Digital supply voltage range compatible with 3.3 V and 5 V MCU

– Bulb inrush mode (BIM) to drive 2 W lamps and electronic loads

– Two independent internal PWM generators for MCU offloads and to

drive LEDs

– Very low quiescent current (with usage of IDLE pin)

– Limp-home mode (with usage of IDLE and IN pins)

– Safety features

◦ Temperature sensor and monitoring

◦ Serial communications using address feedback, 1 parity bit, frame

counter and short frame detection

– Fail-safe activation via input pins

– Safe operation at low battery voltage (cranking)

• Protective functions

– Overcurrent latch off

– Lower supply voltage range for extended operation

– Electrostatic discharge (ESD) protection

– Reverse battery protection on VBATT without external components

– Short circuit battery protection

– Thermal shutdown latch off

• Diagnostic features

– Latched diagnostic information via SPI register

– Overcurrent and overtemperature detection at on state

– Off state diagnosis, able to detect and distinguish open load and short to GND conditions

Applications

• Low-side switches for 12 V in automotive or industrial applications such as lighting, heating, motor driving,

energy and power distribution

• Especially designed for driving relays, LEDs and motors
