Abstract
A load switch circuit implemented on an IC chip includes a first node for coupling to an input voltage, a second node for coupling to an external load, first and second capacitor nodes for coupling to first and second terminals of an external capacitor, and a first PFET coupled between the first node and the second node to control an output voltage to the external load. The load switch circuit also includes a driver circuit having a first NFET that has a drain coupled to the first node and a source coupled to a gate of the first PFET. A slew-rate-control circuit is coupled to a gate of the first NFET and includes the first capacitor node, which is coupled to the gate of the first NFET, and the second capacitor node, which is coupled to the second node.
