In the SCM system, MCU needs reset circuit, which can use R-C reset circuit or reset circuit achieved by reset chip. R-C reset circuit is economic. But it is not ratherreliable. The reset circuit achieved by reset chip is with high reliability. Therefore, in order to ensure the reliability of reset circuit, the system uses reset circuit achieved by reset chip. The system uses a MAX809 chip. And reset circuit is as shown below. In order to reduce the interference of power supply, a 0.1μF capacitor is also needed to be placed on a reset chip's power input legs. Such can achieve the filtering and reduce disruption of the input end.
