Abstract
The present disclosure relates to a power circuit including a power supply circuit and a first control circuit. The power supply circuit is electrically connected to a power supply source and a power terminal for selectively providing power to the power terminal. The first control circuit is electrically connected to the power supply circuit and configured to receive a detection signal to enable or disable the power supply circuit. When the detection signal is enabled, the first control circuit provides a first enable signal to the power supply circuit, so that the power supply circuit provides power to the power terminal. When the detection signal is at the disable level, the first control circuit is configured to provide the first disable signal to the power supply circuit, so that the power supply circuit stops providing power from the power supply source to the power terminal.
