Working Principles

The UJA1075ATW/3V3/1J is designed to facilitate reliable communication in automotive applications using the Controller Area Network (CAN) protocol. It acts as a transceiver, converting digital signals from the microcontroller into differential voltage signals suitable for transmission over the CAN bus. The transceiver also receives differential voltage signals from the bus and converts them into digital signals for the microcontroller.

The IC incorporates various protection features such as overvoltage, undervoltage, overtemperature, and short-circuit protection to ensure the integrity of the communication system. It supports both local and remote wake-up functionality, allowing the device to enter low-power standby mode and wake up upon receiving specific wake-up patterns on the bus.
