Abstract: This disclosure includes systems, methods, and techniques for controlling delivery of power to a load. For example, a circuit includes a first switching device and a second switching device. The circuit is configured to activate, in response to a source voltage of a semiconductor device being lower than a first voltage, the first switching device in order to cause the circuit to deliver a first electrical signal to the semiconductor device, where the first electrical signal includes the first voltage and deactivate the first switching device in response to the source voltage of the semiconductor device not being lower than the first voltage. Additionally, the circuit is configured to activate, in response to the source voltage of the semiconductor device not being lower than the first voltage, the second switching device to cause the circuit to deliver a second electrical signal to the semiconductor device.

Abstract: An electrostatic discharge clamp for groups of terminals having cascaded and different voltage classes, a plurality of discharge paths, and a multiple-input trigger circuit. In response to detecting a positive voltage event at any of the groups of terminals, the trigger circuitry can turn on an electronic switch causing current caused by the voltage event to flow through one or more of the discharge paths instead of through functional circuitry which could potentially be damaged by the current caused by the voltage event.
