ABSTRACT:
A system includes a current sense amplifier to receive an input voltage based on a sense current provided to load circuitry. The current sense amplifier is configured to generate an output voltage from the input voltage based, at least in part, on one or more reconfigurable characteristics of the current sense amplifier. The system also includes a microcontroller to compare the output voltage from the current sense amplifier to one or more programmable thresholds. The microcontroller is configured to direct a current controller to regulate the sense current provided to the load circuitry according to the comparison.
