TJA1027T/20,118 Datasheet PDF - NXP

●The TJA1027T/20,118 is a LIN 2.2A/SAE J2602 Transceiver 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 and SAE J2602. The interface between the Local Interconnect Network (LIN) master/slave protocol controller and the physical bus in a LIN network. The TJA1027 is pin-compatible with the TJA1020 and the TJA1021. 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 master application, an external resistor in series with a diode should be connected between pin VBAT and pin LIN. The receiver detects a receive data stream on the LIN bus input pin and transfers it via pin RXD to the microcontroller.

● 20kBd Baud rate

● Very low current consumption in sleep mode with remote LIN wake-up

● Passive behaviour in unpowered state

● Operational during cranking pulse - Full operation from 5V upwards

● Under-voltage detection

●All input and output pins are protected against ESD under normal handling. When handling ensure that the appropriate precautions are taken.
