Abstract:
In an example embodiment, a device comprises a gate driver and a current detector circuit. The gate driver is configured to be coupled to a power switch on the VBUS line of a USB connector. The current detector circuit is configured to be coupled to the VBUS line and comprises a current sense amplifier, a reference voltage generator circuit, and a comparator. The current sense amplifier is configured to receive a pair of input voltages and to output an indicator signal responsive to the input voltage difference. The reference voltage generator circuit comprises a digital-to-analog converter configured to generate a reference voltage signal based on a received voltage selector signal that is a binary input signal comprising multiple bit values. The comparator is configured to receive the indicator signal and the reference voltage signal and to output an interrupt signal responsive to the indicator signal exceeding the reference voltage signal.

Claim (Index 31):
A system comprising:\n a universal serial bus (USB) connector comprising a voltage bus (VBUS) line; a power switch coupled inline on the VBUS line and configured to turn off in response to an interrupt signal; a sense resistor coupled in series with the power switch on the VBUS line; and a current detector circuit coupled to the VBUS line, the current detector circuit comprising:\n a current sense amplifier configured to sense an input voltage difference across the sense resistor and to output an indicator signal responsive to the input voltage difference; \n a reference voltage generator circuit comprising a digital-to-analog converter and configured to receive a voltage selector signal, wherein the digital-to-analog converter is configured to generate a reference voltage signal based on the voltage selector signal, and wherein the voltage selector signal is a binary input signal comprising multiple bit values; and \n a comparator coupled to the current sense amplifier and to the reference voltage generator circuit, wherein the comparator is configured to receive the indicator signal and the reference voltage signal and to output the interrupt signal responsive to the indicator signal exceeding the reference voltage signal.
