Abstract: A device for controlling an electronic switch between a power supply and a load includes a sensing circuit to measure a current to the load and a control circuit to control operation of the electronic switch if the current exceeds a current limit. The control circuit includes a normal current circuit to output a first switch control current to the electronic switch and a boost current circuit to output a second switch control current to the electronic switch, the first switch control current being higher than the second switch control current.

Abstract: In an example, a device for controlling an electronic switch between a power supply and a load includes a first device pin configured to be in communication with the electronic switch, a sensing circuit configured to be connected to an input voltage and to measure a current to the load, a control circuit configured to be in communication with the sensing circuit and the electronic switch, the control circuit configured to use a current limit signal to control operation of the electronic switch, and a current limit circuit configured to be in communication with the control circuit, the current limit circuit configured to generate the current limit signal representing a current limit and automatically adjust the current limit signal in response to a change in at least one of the input voltage and an output voltage.
