ZXGD3112N7中文资料400V ACTIVE OR-ING FET CONTROLLER数据手册Diodes规格书

描述 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.

简介

ZXGD3112N7属于集成电路（IC）的OR控制器理想二极管。由制造生产的ZXGD3112N7OR 控制器，理想二极管理想二极管控制器也称为 OR-ing 控制器，可用于以仅允许单向电流的方式控制外部通道晶体管（通常为 FET），类似于整流二极管，但传导损耗低得多。在其他应用中，它们通常用于在为了冗余和增加电流输出能力而并行连接的电源中提供逆流保护。
