主要介绍了以PIC18F2480单片机为处理器，基于可编程多路开关检测接口器件MC33993实现的车用多路开关检测接口电路的设计。该设计克服了以往基于分立元件的检测接口电路的弊端，简化了接口电路设计，保证了车用开关工作的可靠性和安全性。
Abstract:
The design of automotive multiple switch detection interface circuit based on MC33993 is introduced mainly which adopts PIC18F2480 single chip microprocessor.This circuit overcomes shortage of traditional design which contains many schism elements, and the application of MC33993 also predigests the whole design of interface circuit and guarantees the dependability and security of the switch.
