A control circuit includes a control chip and a protection circuit module. A first output port and a second output port of the protection circuit module are electrically connected to a load. An overcurrent protection resistor is electrically connected between the second output port and a ground. A thermistor and a node between the overcurrent protection resistor and the second output port are electrically connected to the comparator unit. A bypass switch is electrically connected to the comparator unit, the ground, and the control chip. When a current flowing through the overcurrent protection resistor is greater than an overcurrent protection threshold, or when a resistance of the thermistor overranges an over temperature protection range, the bypass switch bypasses the first output port to the ground for bypassing the load. The control circuit is reliable and miniaturized with overcurrent protection and over temperature protection in an integrated circuit.
