Description
ZXGD3112N7 is a 400V Active OR'ing 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.
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 OR'ing 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.
