ZXGD3108N8TC

ZXGD3108N8TC is a 40V active o-ring MOSFET controller. It is 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. It can be used on both high-side and low-side power supply units (PSU) with rails upto ±40V. During PSU fault conditions, the OR’ing controller detects the power reduction and rapidly turns off the MOSFET in <lt/>600ns to block reverse current flow and avoid the common bus voltage dropping. It is used in applications such as (N+1) redundant power supplies, telecom and networking, data centres, and servers.
