OR'ing Controller from Diodes Incorporated Raises UPS Reliability

PLANO, Texas--(BUSINESS WIRE)--

Diodes Incorporated DIOD, a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the ZXGD3108N8 controller. This 40V-rated active OR'ing controller helps increase the reliability of uninterruptible power supplies (UPS) in telecom, data centers and server duties. The ZXGD3108N8 is designed to fully enhance very low R_DS(ON) power MOSFETs, enabling lossy Schottky blocking diodes to be replaced and resulting in lowered operating temperature and increased UPS system integrity.

By driving MOSFETs in this way, the controller also improves the overall system efficiency of standard 12V and 24V common rail systems. Compared to alternative devices, the ZXGD3108N8 offers the lowest turn-off threshold voltage. At less than -3mV, and with a tight tolerance of ±2mV, system stability and efficiency is improved under light load conditions.

Additionally, the controller is able to sink a current of 5A, ensuring the fastest possible discharge of the paralleled OR'ing MOSFETs. At just 600ns, turn-off is fast to avoid reverse-current flow and prevent voltage dropping on the common rail. In a typical 12V configuration, device quiescent current is specified as sub 400µA and standby power consumption less than 5mW.
