Description:
The MCP2021/2/1P/2P provides a bidirectional, half-
duplex communication physical interface to automotive
and industrial LIN systems that meets the LIN bus
specification Revision 2.1 and SAE J2602-2. The
devices incorporate a voltage regulator with 5V at
50 mA or 3.3V at 50 mA regulated power-supply
outputs.
The regulator is short-circuit protected, and is protected
by an internal thermal shutdown circuit. The 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.
The MCP2021/2/1P/2P family of devices includes the
following packages.
