10.1 Overview

The TPIC1021A is a LIN (Local Interconnect Network) physical layer transceiver which integrates a serial transceiver with wake-up and protection features. The LIN bus is a single-wire, bidirectional bus that typically is used in low speed in vehicle networks with data rates that range from 2.4 kbps to 20 kbps.
