Abstract
The invention provides a control circuit of a switch device. A single output pin of the control unit outputs an enable signal to control terminals of two switch units to control an on-state of the two switch units, and adjust a current size of a control current of the on-state of the switch device. One of the switch units after receiving the enable signal for a predetermined time is switched to an off-state, so as to reduce power consumption of the switch device.
