SIT1021 Local Interconnect Network (LIN) transceiver
■The SIT1021 is a physical layer transceiver of Local Interconnect Network (LIN). It is compliant with LIN 2.0/LIN 2.1/LIN 2.2/LIN 2.2A/ISO 17987-4:2016 (12V) and SAE J2602 standards. It is typically used for low speed in-vehicle networks using baud rates from 1 kBd to 20 kBd. The LIN protocol data stream at the transmit data input (TXD) is converted by the SIT1021 into a bus signal with optimized wave shaping to minimize ElectroMagnetic Emission (EME). The SIT1021 converts the data stream on LIN bus to logic level signals that are sent to the microprocessor via the pin RXD. The LIN bus is pulled high by the internal slave resistor and a series diode. Master applications require an external pull-up resistor in series with a diode to connect pin VBAT and pin LIN.
■The SIT1021 has an extremely low current consumption in sleep mode. The power consumption is reduced to a minimum if in failure modes. It also provides a high voltage output pin INH to enable an external high voltage regulator which used to support the microprocessor.
