The TJA1124 is a quad Local Interconnect Network (LIN) master channel device. It provides the interface between a LIN master protocol controller and the physical bus in a LIN network. Each of the four channels contains a LIN transceiver and LIN master termination.
The TJA1124 is primarily intended for in-vehicle sub-networks using baud rates up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 (12 V LIN) and SAE J2602-1.
Power consumption is very low in Low Power mode. However, the TJA1124 can still be woken up via pins SLP and LIN1 to LIN4.
