Product Summary
The TJA1020T/N1 is an interface between the LIN master/slave protocol controller and the physical bus in a Local Interconnect Network (LIN). The TJA1020T/N1 is primarily intended for in-vehicle sub-networks using baud rates from 2.4 up to 20 Kbaud. The transmit data stream of the TJA1020T/N1 at the TXD input is converted by the LIN transceiver into a bus signal with controlled slew rate and wave shaping to minimize 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 INH or pin BAT and pin LIN. The receiver detects the data stream at the LIN bus input pin and transfers it via pin RXD to the microcontroller.
