Abstract: A switching circuit controls the flow of current between its input and output in accordance with the state of a control signal applied to the circuit. When the control signal is in a first state and the voltage applied to the input is higher than the voltage at the output, the circuit provides a low resistance path between its input and output terminals thereby enabling current to flow from the input to the output.

When the control signal is in a second state, the circuit is turned off thus inhibiting current flow between the input and the output.
