TJA1124

TJA1124 Quad LIN master transceiver Rev. 1 — 8 May 2018 Product data sheet 1 General description 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 subnetworks 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. The transmit data streams generated by the LIN master protocol controller are converted by the TJA1124 into optimized bus signals shaped to minimize ElectroMagnetic Emission (EME). The LIN bus output pins are pulled HIGH via internal LIN master 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, the TJA1124 can still be woken up via pins SLP and LIN1 to LIN4. 2 Features and benefits 2.1 General Four LIN master channels in a single package: – LIN transceiver – LIN master termination consisting of a diode and a 1 kΩ ±10 % resistor Compliant with: – LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A – ISO 17987-4:2016 (12 V LIN) – SAE J2602-1 Very low current consumption in Low Power mode with wake-up via SLP or LIN pins Option to control an external voltage regulator via the INH...
