Micro-controller reset system and reset method thereof
A reset system comprises an enable circuit, a buck converter and a reset circuit. The enable circuit is connected to a system power source. When a voltage of the system power source is greater than a first voltage, the enable circuit outputs an enable signal with a steep leading edge. The buck converter converts the system power source to a micro-controller power source according to the enable signal. The reset circuit is connected to the system power source and the micro-controller power source. When a voltage of the system power source is less than a second voltage, the reset circuit outputs a reset signal to reset the micro-controller. The first voltage is smaller than the second voltage.
