摘要： A phase detection circuit includes first to third power input modules, first to third power input terminals, an alarm module, first to fifth electronic switches, and a power management module. The power input modules are used to convert pulse signals from a multi-phase power supply into direct current voltages and output the direct current voltages to the first to third electronic switches. When the multi-phase power supply operates abnormally, no direct current voltages are output to the first to third electronic switches and the alarm module alarms.

摘要： A load-testing circuit is used for simulating maximum standard load currents for different types of USB ports. The load-testing circuit includes a first electronic switch, a second electronic switch, and a current selection module including a plurality of current branch circuits. When one of the current branch circuits is activated, a voltage at a third terminal of the first electronic switch is supplied to a first terminal of the second electronic switch through the activated current branch circuit to turn on the second electronic switch. A current of the third terminal of the first electronic switch is approximately equal to a current of the activated current branch circuit.
