SYNCHRONOU S R E CTIFIER CONTROLLER

Description

The ZXGD3101 is intended to drive MOSFETS configured as ideal

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.
