Abstract

A current detector circuit includes a current sense amplifier, coupled to a sense resistor, to receive a pair of input voltages and to output a first indicator signal responsive to a sensed input voltage difference produced by a sensed current passing through the sense resistor. The current detector circuit includes a comparator coupled to the current sense amplifier, the comparator to compare the first indicator signal to a reference voltage signal and output an interrupt signal responsive to the first indicator signal exceeding the reference voltage signal; and a reference voltage generator circuit coupled to the comparator, the reference voltage generator circuit to select the reference voltage signal from a plurality of reference voltages according to a first selector signal received from a configuration channel of a serial bus connector device.
