基于MC33972芯片的一种开关检测电路的设计及实现
资料介绍
提出了一种新型的开关量检测电路的方法，通过汽车电控单元与可编程多路开关检测接口器件MC33972芯片之间进行SPI通信来实现，将之与传统的分立元件组成的开关量检测电路相比，电路设计简单，保证了车用开关工作的可靠性和有效性。
A new method based on MC33972 for the automobile switch detection circuit is introduced, which is achieved by the SPI communication between the automobile electronic control unit and the MC33972 which is the programmable low-power multiehannel switch detection interface chip. This method is simpler than the traditional switch detection circuit which contains many schism ele- ments and can guarantee the dependability and the security of the automobile switch.
