onsemi NCV7422MW0R2G, LIN Transceiver 0.02Mbps, 14-Pin DFN

The ON Semiconductor NCV7422 is a two channel physical layer device using the Local Interconnect Network (LIN) protocol. It allows interfacing of two independent LIN physical buses and the LIN protocol controllers. The device is compliant to ISO 17987-4 (LIN 2.x Protocol Specification package) and the SAE J2602 standard. The NCV7422 LIN device is a member of the in-vehicle networking (IVN) transceiver family. The LIN bus is designed to communicate low-rate data from control devices such as door locks, mirrors, car seats, and sunroofs at the lowest possible cost. The bus is designed to eliminate as much wiring as possible and is implemented using a single wire in each node. Each node has a slave MCU-state machine that recognizes and translates the instructions specific to that function. The main attraction of the LIN bus is that all the functions are not time critical and usually relate to passenger comfort.
