TJA1027T/20/2Z is an ISO 17987/LIN 2.x/SAE J2602 transceiver. It is the interface between the Local Interconnect Network (LIN) host/server protocol controller and the physical bus in a LIN network. It is primarily intended for in-vehicle sub-networks using baud rates up to 20kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, SAE J2602 and ISO 17987-4:2016 (12V). The TJA1027 is pin-compatible with the TJA1020, TJA1021, TJA1022, TJA1029 and MC33662(B). The transmit data stream generated by the protocol controller is converted by the TJA1027 into an optimized bus signal shaped to minimize ElectroMagnetic Emissions (EME). The LIN bus output pin is pulled HIGH via an internal termination resistor. For a host application, an external resistor in series with a diode should be connected between pin VBAT and pin LIN. The receiver detects a received data stream on the LIN bus input pin and transfers it via pin RXD to the microcontroller.
