Abstract: An operating circuit including a system circuit and a power control circuit is provided. The system circuit operates according to the voltage of the node. The power control circuit includes a first connection port, a second connection port, a first always-on switch, a second always-on switch, a first current limiter, and a second current limiter. The first connection port is configured to receive first power provided by a first external device. The second connection port is configured to receive second power provided by a second external device. The first always-on switch is coupled to the first connection port to transmit the first power. The second always-on switch is coupled to the second connection port to transmit the second power. The first current limiter is coupled between the first always-on switch and the node. The second current limiter is coupled between the second always-on switch and the node.

Abstract: A power control circuit includes a detection device, a first control device, and a second control device. When the detection signal is changed from lower to higher than the first voltage, the first control device's output is changed to the second potential. When the detection signal is changed from higher to lower than the second voltage, the first control device's output is changed to the first potential. When the detection signal is changed from lower to higher than the third voltage, the second control device's output is changed to the fourth potential. When the detection signal is changed from higher to lower than the fourth voltage, the second control device's output is changed to the third potential. According to the first or second potentials, the circuit device turns on/off the first function. According to the third or fourth potentials, the circuit device turns on/off the second function.

Abstract: A discharging circuit discharging electrical charges of an external energy storage device coupled to a power transmission line coupled between a power supply device and a load is provided. The discharging circuit includes a current-limiting unit, an internal energy storage unit, a voltage detection unit and a discharge unit. The current-limiting unit is coupled between the power transmission line and a first node. The internal energy storage unit is coupled between the first node and a ground node. The ground node receives a ground level. The voltage detection unit detects a level of the first node. The discharge unit is coupled between the power transmission line and a second node. When the level of the first node is less than a pre-determined level, the voltage detection unit directs the second node to couple to the ground node.
