diode replacements. The device is comprised of a differential amplifier
detector stage and high current driver. The detector monitors the
reverse voltage of the MOSFET such that if body diode conduction
occurs a positive voltage is applied to the MOSFET’s Gate pin.
Once the positive voltage is applied to the Gate the MOSFET
switches on allowing reverse current flow. The detectors’ output
voltage is then proportional to the MOSFET Drain-Source reverse
voltage drop and this is applied to the Gate via the driver. This action
provides a rapid turn off as current decays.
