MCP200x 应用:

The MCP2003/4 transceivers are appropriate for applications in the automotive market, including rain sensors, sunroofs, window lift and many other sensor or actuator-based systems. The devices are also appropriate for many non-automotive applications, including those in the industrial (e.g. large lawn mowers, golf carts, metering and door locks); medical (e.g. motors and control panels on wheel chairs, and hospital beds); and appliance markets (e.g. washing machine and stove control panels and sensors).
