TJA1027
ISO 17987/LIN 2.x/SAE J2602 transceiver
Rev. 3 — 18 December 2018
Product data sheet
1. General description
The TJA1027 is the interface between the Local Interconnect Network (LIN) master/slave 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, SAE J2602 and ISO 17987-4:2016 (12 V). 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.
