Overview
Features
Features
General
- Designed for automotive applications ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant high-speed CAN transceiver
- Hardware and software compatible with the UJA116x product family and with improved EMC performance
- ±8 kV ESD protection, according to the Human Body Model (HBM) on the CAN bus pins
- ±6 kV ESD protection, according to IEC TS 62228 on the CAN bus pins, VEXT and on pins BAT and WAKE
- CAN bus pins short-circuit proof to ±58 V
- Battery and CAN bus pins are protected against automotive transients according to with ISO 7637-3
CAN transceiver
- High-speed CAN transceiver supporting CAN FD active communication up to 5 Mbit/s in the CAN FD data field
- Autonomous bus biasing according to ISO 11898-6
- Remote wake-up capability via standard CAN wake-up pattern or via ISO 11898-6 compliant selective wake-up frame detection, including CAN FD-passive support
Integrated voltage regulator (V1)
- Integrated 5 V / 100 mA voltage regulator for microcontroller supply
- Support for microcontroller RAM retention down to a battery voltage of 2 V
Sensor supply regulator (VEXT)
- Integrated 5 V / 30 mA voltage regulator for sensor supply
- Protected against short-circuits to GND and to the battery (can handle negative voltages as low as -18 V)
System control features
- Standby and Sleep mode featuring very low supply currentM
- Transmit data (TXD) dominant time-out functionM
- Mode control via the Serial Peripheral Interface (SPI)M
- Watchdog with independent clock sourceM
- Local wake-up via the WAKE pinM
- High-voltage output (INH) for controlling an external voltageM
- Configuration of selected functions via non-volatile memoryM
