Fully compliant with the ISO 11898 standard, it supports data rates up to 1 Mbps and provides differential transmit and receive capability. The device features very low electromagnetic emission, excellent electromagnetic immunity, and a standby mode consuming only 10uA, making it ideal for automotive and industrial CAN bus applications where power consumption and EMC compliance are critical.","working_principle":"The TJA1050T operates as a differential bus transceiver for the Controller Area Network protocol. **Transmit Path**: The TXD input from the CAN controller drives the bus driver, which generates the differential voltage between CANH and CANL. A dominant bit (TXD=low) drives CANH high (3.5V) and CANL low (1.5V), producing 2V differential. A recessive bit (TXD=high) releases both lines to 2.5V (zero differential). **Receive Path**: The differential receiver continuously monitors the CANH-CANL voltage and outputs the decoded logic level on RXD to the CAN controller. The receiver operates even in standby mode (with very slow response) for remote wake-up detection. **Bus Protection**: CANH and CANL pins are protected against short circuits to +\/-18V, and provide ESD protection greater than 4kV. The common mode range extends from -12V to +12V, ensuring reliable communication in noisy automotive environments. **Standby Mode**: The S pin controls operating mode. When S is high, the device enters standby mode drawing only 10uA. A dominant bit on the bus in standby mode generates a wake-up signal.","pin_description":"
