Abstract
An integrated circuit includes a processor coupled to a voltage bus of a cable and located within a universal serial bus (USB) compatible power supply device. A current sense amplifier (CSA) is coupled to a sense resistor to monitor a current of the voltage bus. A first comparator is coupled to the CSA and the processor and to trigger in response to detecting that a monitored current value from the CSA is greater than or equal to a first reference value, which includes a hysteresis offset value. An analog-to-digital converter (ADC) is coupled to the CSA and the processor. In response to detecting trigger of the first comparator, the processor is to trigger the ADC to measure an absolute current value of voltage bus, and cause an additional voltage, equal to a voltage drop across the cable based on the absolute current value, to be supplied to the voltage bus.
