ACTIVE OR’ING CONTROLLER
Description
The ZXGD3102 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.
