SYNCHRONOUS MOSFET CONTROLLER

Description
The ZXGD3113W6 is intended to drive a MOSFET configured as an
ideal diode replacement. 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 the 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.

Description and Function
Reference
This pin is connected to VCC via a resistor, RREF. RREF sets the source current into this pin
Bias
This pin is connected to VCC via a resistor, RBIAS. RBIAS sets the source current into this pin.
Power Supply
This is the supply pin. It is recommended to decouple this point to Ground closely with a ceramic capacitor.
Gate Drive
This pin sources and sinks current to and from the synchronous MOSFET Gate.
Ground
This is the ground reference point. Connect to the synchronous MOSFET Source terminal.
Drain
This pin is connected to the Drain pin of the synchronous MOSFET.
