摘要： This invention provides a power switch circuit and a power circuit using the power switch circuit. In particular, the power switch circuit includes a first reverse current monitoring circuit and a second reverse current monitoring circuit. The first reverse current monitoring circuit is coupled to a power transistor, and is configured to detect whether a reverse current flows through the power transistor to a voltage input terminal for a predetermined period of time, and only if yes, turn off the power transistor. The second reverse current monitoring circuit is coupled to the power transistor, and is configured to detect whether a reverse current flows through the power transistor to the voltage input terminal, and if yes, turn off the power transistor immediately. As such, the reverse current can be blocked in time from further flowing to the voltage input terminal, thereby avoiding a damage to the interior electronic components of the power source at the low voltage side.

摘要： A cable drop compensation circuit includes a current detection circuit, a compensation judgment circuit, and a compensation circuit. The current detection circuit detects a load current supplied to a load by a DC output circuit, so as to generate a current detection signal. The compensation judgment circuit receives the current detection signal, and generates a judgment signal when judging the load current higher than a predetermined compensation value. When receiving the judgment signal, the compensation circuit generates a compensation signal. In response to the compensation signal, the DC output circuit raises an output voltage by a compensation voltage.

摘要： A power supply device is provided. The power supply device includes a power transistor, a detection circuit and a driving circuit. The power transistor is controlled by the driving circuit to generate an output current. A first end of the power transistor is coupled to a power voltage pin through a first bonding wire. A second end of the power transistor is configured to output the output current. The detection circuit is coupled between two ends of the first bonding wire to detect the output current and generate a control signal. The driving circuit generates a driving signal according to the control signal. When the output current value is larger than or equal to an over-current-protection current value, the driving circuit starts to adjust a voltage value of the driving signal, such that the output current value is kept at the over-current-protection current value.
