400V ACTIVE OR-ING MOSFET CONTROLLER IN SO7
Description
Features
The ZXGD3112N7 is a 400V active ORing MOSFET controller
designed for driving a very low RDS(ON) power MOSFET as an ideal
diode. This replaces the standard rectifier to reduce the forward
voltage drop and overall increase the power transfer efficiency.

Active OR-ing MOSFET Controller for High- or Low-Side PSU
Ideal Diode to Reduce Forward Voltage Drop
-3mV Typical Turn-Off Threshold with ±2mV Tolerance
400V Drain Voltage Rating
25V VCC Rating
The ZXGD3112N7 can be used on both high-side and low-side power
supply units (PSU) with rails up to ±400V. It enables very low RDS(ON)
MOSFETs to operate as ideal diodes as the turn-off threshold is
only -3mV with ±2mV tolerance. In the typical 48V configuration, the
standby power consumption is <50mW as the low quiescent supply
current is <1mA. During PSU fault condition, the ORing controller
detects the power reduction and rapidly turns off the MOSFET in
<600ns to block reverse current flow and avoid the common bus
voltage dropping.
<50mW Standby Power with Quiescent Supply Current <1mA
<600ns Turn-Off Time to Minimize Reverse Current
