Abstract:
A slew-rate-control (SLC) circuit is coupled to an input for a driver circuit to provide a first binary value when the circuit is powered on and to control a slew rate when a pass element controlled by the driver circuit is enabled. The SLC circuit includes a capacitor node for coupling to a first terminal of an external capacitor, the capacitor node being coupled to the input. The SLC circuit also includes a SLC element coupled between the input and a first source of voltage to define the slew rate and a reset FET coupled between the input and a second source of voltage. The reset FET's gate is controlled by an over-current-protection signal that changes binary value when a short is detected. The reset FET is coupled to return the input to the first binary value responsive to detection of a short
