A reverse current sensing (RCS) regulator system and method is provided. One embodiment of the invention includes a RCS regulator system. The system comprises a RCS comparator that monitors a drain voltage of a LS FET and is configured to switch states at a zero crossing point to provide an indication of the start of a reverse current condition. The system further comprises a RCS evaluator that measures a drain voltage of the LS FET upon receiving an indication that the LS FET has been turned off by the driver logic circuit and adjusts an offset to the RCS comparator to adjust the trip point of the RCS comparator relative to the drain voltage if the measured drain voltage falls outside a predetermined threshold.
