ZXGD3101N8
SYNCHRONOUS RECTIFIER 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 rapi...
