    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

    Abstract: An IC chip, a system and a method of operating the IC chip in response to an event trigger are provided. The method includes responsive to the event trigger, coupling a pin to a source of constant current to charge an external capacitor coupled to the pin and monitoring a capacitor voltage on the pin. If the magnitude of the capacitor voltage is greater than a rising threshold, detection of a falling threshold is enabled. If the magnitude of the capacitor voltage is greater than a voltage threshold, a first response is triggered and the pin is coupled to the lower rail to discharge the external capacitor. If detection of the falling threshold is enabled and the magnitude of the capacitor voltage is less than the falling threshold, the first response is also triggered.

    Abstract: Apparatus disclosed herein implement a fast transient precision current limiter such as may be included in an electronic voltage regulator. The current limiter includes two current sense element/current clamp control loops. A fast response time control loop first engages and clamps a current spike. A precision control loop then engages to more accurately clamp the output current to a programmed set point. The precision clamping loop includes an inner loop to linearize the precision current sense element. The inner loop forces the drain-to-source voltage (VDS) of the precision sense element to track the VDS of the regulator pass element. A more precise clamping operation results. Overall speed is not sacrificed as the fast response time clamping loop operates in parallel to protect circuitry while the precision clamping loop engages.
