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. MCP2021/2 family
