Microchip Technology MCP2021/2 LIN Transceiver with Voltage Regulator
Microchip Technology MCP2021/2 LIN Transceiver with Voltage Regulator provides a bidirectional, half-duplex communication physical interface to automotive and industrial LIN systems that meets the LIN bus specification Revision 2.0. The devices incorporate a voltage regulator with 5V at 50mA or 3.3V at 50mA regulated power-supply outputs. This regulator is short-circuit protected and includes an internal thermal shutdown circuit. This device has been specifically designed to operate in the automotive operating environment and will survive all specified transient conditions while meeting all of the stringent quiescent current requirements.
