摘要:
An electronic device includes a power input pin receiving a voltage from an external power supply, a load, and a surge suppression circuit connected between the power input pin and the load. The surge suppression circuit includes a first transistor, a voltage divider circuit and a capacitor. The first transistor includes a control end, a first conductive end connected to the power input pin, and a second conductive end connected to the load. The voltage divider circuit includes a common node connected to the control end, one end of the voltage divider circuit connected between the first conductive end and the power input pin, and the other end of the voltage divider circuit connected to ground. One end of the capacitor is connected between the second conductive end and the load, and the other end of the capacitor is connected to the control end.
