TJA1124AHG/1Z

TJA1124AHG/1Z is a quad local interconnect network (LIN) commander transceiver channel device. It provides the interface between a LIN commander protocol controller and the physical bus in a LIN network. Each of the four channels contains a LIN transceiver and LIN commander termination. This is primarily intended for in-vehicle subnetworks using baud rates up to 20KBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 (12V LIN) and SAE J2602-1. The transmit data streams generated by the LIN commander protocol controller are converted by the TJA1124 into optimized bus signals shaped to minimize Electromagnetic Emission (EME). The LIN bus output pins are pulled HIGHVia internal LIN commander termination resistors. The receivers detect receive data streams on the LIN bus input pins and transfer them to the microcontroller via pins RXD1 to RXD4. Power consumption is very low in Low Power mode. However, this can still be woken up via pins SLP and LIN1 to LIN4.
