NCV7321D12R2G developed by ON Semiconductor belongs to the in−vehicle networking (IVN) transceiver family. This stand-alone LIN transceiver is specifically designed to interface between a LIN protocol controller and the physical bus. Using the I3T technology, both high−voltage analog circuitry and digital functionality to co−exist on the same chip can be realized. It is able to communicate low-rate data from control devices at the lowest possible cost.
