TPIC1021A-Q1 LIN Physical Interface

The TPIC1021A is the Local Interconnect Network (LIN) physical interface, which integrates the serial transceiver with wake-up and protection features. The LIN bus is a single-wire bidirectional bus typically used for low-speed, in-vehicle networks using data rates between 2.4 kbps and 20 kbps. The LIN protocol output data stream on TXD is converted by the T.
