摘要： 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.

摘要： An exemplary charge indicator circuit indicates the state of charge of a battery. The charge indicator circuit includes a connection jack, an indicator module, a voltage detection module, a charger IC, and a path connection module. The indicator module includes an indicator. The indicator is on when the battery is being charged. The voltage detection module is to output a first response signal when the connection jack is connected to the power supply. The charger IC is to manage the charging of the battery, and output a low level signal when a condition of the battery is satisfied. The path connection module is in a shunt circuit of the indicator module, and enables the shunt circuit of the indicator module to cause the indicator to be on when the voltage detection module outputs the first response signal and the charger IC outputs the low level signal.

摘要： A protection method is executed by an electronic device that is powered by a supply voltage of a power source. The protection method includes steps of: storing a power-off threshold voltage; detecting the supply voltage of the power source to generate a detecting voltage; determining whether the detecting voltage is equal to the power-off threshold voltage; beginning to count for a predetermined period of time when the detecting voltage is equal to the power-off threshold voltage and acquiring the detecting voltage during the predetermined period of time; determining whether each acquired detecting voltage is smaller than the power-off threshold voltage; and generating a first control signal when one of the acquired detecting voltages is larger than or is equal to the power-off threshold voltage; wherein the first control signal controls a processor of the electronic device to stop performing a power-off procedure.
