NXP TJA1021BT/0Z LIN Transceiver, 5.5 to 27 V Supply, 20 Kbaud, -40 °C to 150 °C, SOIC-8

TJA1021BT/0Z is a ISO 17987/LIN 2.x/SAE J2602 transceiver. It is a interface between the local interconnect network (LIN) commander/ responder protocol controller and the physical bus in a LIN. It is primarily intended for in vehicle sub-networks using baud rates from 1kBd upto 20kBd (/20 and B variants) and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, SAE J2602 and ISO 17987-4:2016 (12V). It is pin-to-pin compatible with the TJA1020 and MC33662(B). The transmit data stream of the protocol controller at the transmit data input (TXD) is converted by into a bus signal with optimized slew rate and wave shaping to minimize ElectroMagnetic Emission (EME). The LIN bus output pin is pulled HIGH via an internal termination resistor. For a commander application, an external resistor in series with a diode should be connected between pin INH or pin VBAT and pin LIN. The receiver detects the data stream at the LIN bus input pin and transfers it via pin RXD to the microcontroller.
