Product Introduction

Overview

The NCV7321D11R2G is a fully featured local interconnect network (LIN) transceiver designed by onsemi to interface between a LIN protocol controller and the physical bus. This transceiver is part of the in-vehicle networking (IVN) transceiver family and is implemented in I3T technology, allowing both high-voltage analog circuitry and digital functionality to co-exist on the same chip. It is designed to operate in harsh automotive environments and is qualified according to the TS16949 flow. The LIN bus is optimized for communicating low-rate data from control devices such as door locks, mirrors, car seats, and sunroofs, aiming to minimize wiring and costs.

Applications

The NCV7321D11R2G is designed for use in automotive applications, particularly in the control of mechatronic nodes such as door locks, mirrors, car seats, and sunroofs. It is part of the in-vehicle networking (IVN) system, which aims to minimize wiring and reduce costs while ensuring reliable communication between various control devices. The LIN bus is especially useful for functions related to passenger comfort, which are not time-critical.
