    摘要: A current control module is employed to protect a conductive feature of a printed circuit board (PCB) from an overcurrent event by comparing a reference voltage output from a compensation circuit connected to a reference power supply to a voltage output from a conductive feature connected to a power supply which is different from the reference power supply. The reference output voltage is representative of an anticipated voltage output from the conductive feature. The current control module is configured to initiate regulation of power to the conductive feature when the voltage output from the conductive feature exceeds the reference voltage output.
