CTL
The ground of the load circuit being protected. Current flows into this pin during normal
operation.
The control pin of the device. A positive voltage to the NEG pin turns the switch on and a
negative voltage turns the switch to a high-impedance state.
The ground of the input power source. Current flows out of this pin during normal operation.
