Active O-Ring MOSFET controller drives low RDS(ON) power MOSFETs as ideal diodes

10-02-2015 | Mouser Electronics | Design & Manufacture

Aimed at applications such as N + 1 redundant power supplies, telecom, networking, data centres and servers, Diodes Inc's. ZXGD3108N8 40V Active O-Ring MOSFET controller is now available from Mouser stock. The device 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 up to ±40V. It enables very low RDS(ON) MOSFETs to operate as ideal diodes as the turn-off threshold is only -3mV with ±2mV tolerance.
