Overview
TJA1021 ISO 17987/LIN 2.
x/SAE J2602 transceiver Rev.
9 — 10 February 2023 Product data sheet 1 General description The TJA1021 is the interface between the Local Interconnect Network (LIN) commander/ responder protocol controller and the physical bus in a LIN.
It is primarily intended for invehicle sub-networks using baud rates from 1 kBd up to 20 kBd (/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 (12 V).
The TJA1021 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 the TJA1021 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 dat...
