TPIC1021DR

Product Summary

The TPIC1021DR is a LIN (Local Interconnect Network) physical interface, which integrates the serial transceiver with wake up and protection features. The LIN bus is a single wire, bi-directional bus typically used for low-speed in-vehicle networks using baud rates between 2.4 kbps and 20 kbps. The TPIC1021DR has two logical values: the dominant state (voltage near ground) represents a logic ‘0’ and the recessive state (voltage near battery) and represents logic ‘1’.
