LIN 2.2A/SAE J2602 Transceiver
The TJA1027 is the interface between the Local Interconnect Network (LIN) leader/follower protocol controller and the physical bus in a LIN network. It is primarily intended for in-vehicle sub-networks using baud rates up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602. 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 leader 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.
Power consumption is very low in Sleep mode. However, the TJA1027 can still be woken up via pins LIN and SLP_N.
