Patent ID: 8421645

Claim:
An electrostatic protector used in a portable electronic device, comprising: an electrostatic conducting unit; an electrostatic protecting unit connected to the electrostatic conducting unit, the electrostatic protecting unit including at least one protecting circuit, each protecting circuit including a diode, the diode having a cathode connected to the electrostatic conducting unit and a grounded anode; wherein each protecting circuit further includes a resistor, one end of the resistor grounded, and another end of the resistor connected to the electrostatic conducting unit; an alert unit; a power supply; a transformer unit including a transformer chip, the transformer chip being a low dropout regulator (LDO) chip including a grounding connector, a voltage input connector, a voltage output connector, and an enable connector; the grounding connector grounded, the cathode of the diode connected to the enable connector, the alert unit connected to the voltage output connector, the power supply connected to the voltage input connector; wherein electrostatic charges on the portable electronic device are transmitted to the electrostatic conducting unit and generate a voltage on the cathode of the diode to break down the diode, such that the electrostatic charges are transmitted to the ground by the broken down diode and the voltage on the cathode of the diode is reduced; the reduced voltage on the cathode of the diode is input to the enable connector to turn on the transformer chip, the transformer chip transforms an electric potential of the power supply into a working electric potential, and outputs the working electric potential to the alert unit to actuate the alert unit.
