特性

Voltage regulator for MCU, 5.0 or 3.3 V, part number selectable, with possibility of usage external PNP to extend current capability and share power dissipation
Extremely low quiescent current in LP modes
Fully protected embedded 5.0 V regulator for the CAN driver
Multiple undervoltage detections to address various MCU specifications and system operation modes
Auxiliary 5.0 or 3.3 V SPI configurable regulator, for additional ICs, with overcurrent detection and undervoltage protection
MUX output pin for device internal analog signal monitoring and power supply monitoring
Advanced SPI, MCU, ECU power supply, and critical pins diagnostics and monitoring
Multiple wake-up sources in LP modes: CAN or LIN bus, I/O transition, automatic timer, SPI message, and VDD overcurrent detection
ISO11898-5 high-speed CAN interface compatibility for baud rates of 40 kb/s to 1.0 Mb/s
Scalable product family of devices ranging from 0 to 1 LIN, compatible to J2602-2 and LIN 2.1
