Description
The MCP2021A/2A provides a bidirectional, half-
duplex communication physical interface to meet the
LIN bus specification Revision 2.1 and SAE J2602-2.
The device incorporates a voltage regulator with 5V or
3.3V 70 mA regulated power supply output. The device
has been designed to meet the stringent quiescent
current requirements of the automotive industry and
will survive +43V load dump transients, and double
battery jumps.
