ZXGD3111N7

Description

ZXGD3111N7 is a 200V Active OR-ing MOSFET controller designed for driving a very low R_DS(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 ZXGD3111N7 can be used on both high-side and low-side power supply units (PSU) with rails up to ±200V. It enables very low R_DS(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
