Abstract
A united power module having an external input and a first input is provided. The united power module includes a load block, a protection circuitry and a detection block. The detection block includes an analog circuitry. The load block and an end of the protection circuitry are electrically coupled to the external input. The load block, the first input, and another end of the protection circuitry are electrically coupled to the detection block. The load block is supplied by an external power received from the external input. The protection circuitry receives the external power and outputs an auxiliary power. The analog circuitry receives a first power from the first input under a normal power supply state, or receives the auxiliary power under an auxiliary power supply state.
