Abstract
A detection device adapted to a connector is provided herein. The connecter includes a first pin and a second pin, and the first pin and the second pin are physically separated and coupled to a first power respectively. The detection device includes a first transistor, a first resistor, a second transistor, and a bias circuit. The first transistor is coupled between the first pin and the first power. The first resistor is coupled between a gate terminal of the first transistor and the first power. A detection signal is generated at the gate terminal of the first transistor. The second transistor is coupled between the gate terminal of the first transistor and a second power. The bias circuit is coupled between a gate terminal of the second transistor and the first pin.
