ZXGD3103
Description
Features
The ZXGD3103 is intended to drive MOSFETS configured as ideal diode replacements. The device is prised 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.
- 5 to15V VCC Range
- Operation Up to 250k Hz
- 180V Drain Voltage Rating
- Proportional Gate Drive to Minimize Body Diode Conduction
- Turn-off Propagation Delay 15ns and Turn-off Time 20ns
- Detector Threshold Voltage ~10m V
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.
- Standby Current 5m A
- Suitable for Discontinuous Mode (DCM), Critical Conduction
Mode (Cr CM) and Continuous Mode...
