It features multiple low-power modes (Standby, Sleep, Go-to-Sleep) with standby current as low as 40\u03bcA and sleep current of 3\u03bcA, making it ideal for always-on automotive battery management. The device supports local and remote wake-up, provides an INH output for voltage regulator control, and includes a VIO pin for 3.3V\/5V I\/O level matching. Packaged in SO-8, it is widely used in automotive CAN FD networks, gateways, and ECUs.","working_principle":"The TJA1043T operates as a physical layer transceiver between the CAN controller and the bus. In Normal mode, it transmits and receives CAN FD frames at up to 5Mbps. The transmitter converts the TXD logic signal into differential bus signals (CANH\/CANL), while the receiver converts differential bus signals back to the RXD logic signal. In Standby mode, the transmitter is disabled but the receiver monitors the bus for wake-up patterns, consuming only 40\u03bcA. In Sleep mode, current drops to 3\u03bcA while a dedicated wake-up receiver still monitors the bus. The INH output controls an external voltage regulator, turning it on when a wake-up event occurs. The VIO pin sets the I\/O voltage level, enabling direct connection to 3.3V or 5V microcontrollers without level shifters.","pin_description":"
