In the SCM system, SCM needs reset circuit. The reset circuit can be reset circuit using R-C circuit and also can be reset circuit using reset chip. R-C reset circuit is economic but is not reliable. The reset circuit using reset chip is with high reliability. So in order to ensure the reliability of the reset circuit system, the ystem uses a MAX809 chip. Reset circuit is as shown in the figure.
In order to reduce the interference of the power supply, a 0.1μF capacitor is needed to be added on the input legs of the reset chip's power supply, thus achieving the filtering function and reducing the interference for the input end.
