The MCP2021/2 provides a bidirectional, half-duplex communication physical interface to automotive, and industrial LIN systems to meet the LIN bus specification Revision 2.0. The device incorporates a voltage regulator with 5V @ 50 mA or 3.3V @ 50 mA regulated power supply output. The regulator is short circuit protected, and is protected by an internal thermal shutdown circuit. The regulator has been specifically designed to operate in the automotive environment and will survive reverse battery connections, +43V load dump transients, and double-battery jumps. The device has been designed to meet the stringent quiescent current requirements of the automotive industry.
