TJA1029T/2Z

TJA1029T/2Z is an ISO 17987/LIN 2.x/SAE J2602 transceiver with TXD dominant timeout. 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 subnetworks using baud rates up to 20 kBd 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-compatible with the TJA1020, TJA1021, TJA1022, TJA1027 and MC33662(B). The protocol controller generates the transmitted data stream. It converts the data stream 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, connect an external resistor in series with a diode 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.
