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
