US Patent 7940505 Low power load switch with protection circuitry

Load switches are relatively common and in use with a variety of applications, and conventional load switches have been designed to have continually operating protection circuitry, which can consume a great deal of power. Here, a load switch integrated circuit (IC) is provided where a controller within the IC activates and deactivates various protection circuits in a sequence, allowing the protection circuit to protect the IC while also reducing power consumption.
