Pb-free; Restriction of Hazardous Substances Directive (RoHS) and dark green
compliant
ISO 11898-2 and ISO 11898-5 compliant high-speed CAN transceiver
Dedicated low dropout voltage regulator for the CAN bus:
Bus connections are truly floating when power is off
SPLIT output pin for stabilizing the recessive bus level
2 × LIN 2.1 compliant LIN transceivers
Compliant with SAE J2602
Downward compatible with LIN 2.0 and LIN 1.3
Low slope mode for optimized EMC performance
Integrated LIN termination diode at pin DLIN
Wake-up via CAN, LIN or local wake-up pins with wake-up source detection
2 wake-up pins:
CAN transceiver and two LIN transceivers
Scalable 3.3 V or 5 V voltage regulator delivering up to 250 mA for a
microcontroller and peripheral circuitry; an external PNP transistor can be
connected for better heat distribution over the PCB
Separate voltage regulator for the CAN transceiver (5 V)
Watchdog with Window and Timeout modes and on-chip oscillator
Serial Peripheral Interface (SPI) for communicating with the microcontroller
ECU power management system
Enhanced ElectroMagnetic Compatibility (EMC) performance
±8 kV ElectroStatic Discharge (ESD) protection Human Body Model (HBM) on the
CAN/LIN bus pins and the wake-up pins
±6 kV ElectroStatic Discharge protection IEC 61000-4-2 on the CAN/LIN bus pins
and the wake-up pins
±58 V short-circuit proof CAN/LIN bus pins
Battery and CAN/LIN bus pins are protected against transients in accordance with
ISO 7637-3
Independent of the microcontroller supply
Significantly improves EMC performance
