UJA1161A Overview
The UJA1161A is a ‘self-supplied’ high-speed CAN transceiver integrating an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 pliant HS-CAN transceiver and an internal 5 V CAN supply. The only supply input is a battery connection. The UJA1161A can be operated in a very-low-current Standby mode with bus wake-up capability.
UJA1161A Key Features
- Hardware and software patible with the UJA116x product family and with improved EMC performance
- Loop delay symmetry timing enables reliable munication at data rates up to 2 Mbit/s in the CAN FD fast phase
- Autonomous bus biasing according to ISO 11898-6
- Fully integrated 5 V supply (VBUF) for the CAN transmitter/receiver
- VIO input allows for direct interfacing with 3.3 V to 5 V microcontrollers
- Bus connections are truly floating when power pin BAT is off
UJA1161A Applications
- 8 kV ElectrStatic Discharge (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 and on pin BAT
- CAN bus pins short-circuit proof to 58 V
- Battery and CAN bus pins are protected against automotive transients according to
- Very low quiescent current in Standby mode
