Abstract
A testing circuit for an interface includes a load feeding circuit and a voltage testing circuit. The load feeding circuit includes a resistance-regulating unit, a first comparator, a pass element, and a capacitor. The resistance-regulating unit is connected to a positive input of the first comparator. A negative input of the first comparator is connected to the capacitor and a first terminal of the pass element. An output of the first comparator is connected to a second terminal of the pass element. A third terminal of the pass element is connected to the interface. The voltage testing circuit includes a second comparator and a display member connected to the second comparator. The voltage of the interface and a reference voltage are input to inputs of the second comparator, and the second comparator outputs a signal to control the display member to display a comparison result.
