Description
The ZXGD3104 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. The detectors’ output voltage is then proportional to the MOSFET
Drain-Source voltage and this is applied to the Gate via the driver.
This action provides a rapid MOSFET turn off at zero Drain current.
