The TJA1040 is the interface between the controller area network (CAN) protocol controller and the physical bus. It is primarily intended for high speed applications, up to 1 MBaud, in passenger cars. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller.
The TJA1040 is the next step up from the TJA1050 high speed CAN transceiver. Being pin compatible and offering the same excellent EMC performance, the TJA1040 also features:
- An ideal passive behavior when supply voltage is off
- A very low-current standby mode with remote wake-up capability via the bus.
This makes the TJA1040 an excellent choice in nodes, which can be in power down or standby mode in partially powered networks.
