Abstract:
A port securing module includes a power gate that is operable to be coupled in series to a power source and to a load. A resistor is coupled in parallel to the power gate. An operational amplifier includes an inverting input and a non-inverting input that couple the operational amplifier in parallel to each of the power gate and the resistor. The operational amplifier also includes an output that is operable to indicate whether a load is coupled to the power gate and, if a load is coupled to the power gate, supply a voltage to activate the power gate such that power is supplied to the load.
