Overvoltage protection circuit and electronic device
摘要
<p>An overvoltage protection circuit is arranged in an electronic device for providing a proper working voltage to the electronic device. The overvoltage protection circuit includes a first selecting circuit and a second selecting circuit connected in parallel to the first selecting circuit between a voltage input port and a voltage output port of the overvoltage protecting circuit. When an input voltage from the input port is less than a first value, the input voltage is output to the output port directly through the first selecting circuit, and when the input voltage is greater than the first value, the input voltage is output to the output port after the value of the input voltage is reduced through the second selecting circuit.
