Abstract
A monolithic solid state power controller generally comprises a power supply, zero voltage crossing detector, operator interface circuitry, current sensing and trip timing logic (having zero current detection capability), drive circuitry, and a power switch. The current sensing and trip timing logic functions are implemented in a monolithic device which provides flexible mode of operation of the switch, operator command validation, status and mode indication, drive enablement in synchronization with zero voltage crossing of the source voltage, and tripout operation in synchronization with zero current crossing in the load current. Both fast trip (in response to catastrophic overcurrent) and timed trip (in response to overcurrent conditions occurring over a period of time) capabilities are provided.
