Abstract
A device includes a power control analog subsystem of a universal serial bus-power delivery (USB-PD) compatible power supply device. The power control analog subsystem includes a programmable current sensing circuit and a current sense resistor coupled to the power control analog subsystem. The power control analog subsystem is configured to concurrently compare a current flow through the current sense resistor with at least three different reference values, e.g., compare a sensed voltage with at least three different reference voltages.
