PI2002集成电路（IC）的OR控制器理想二极管规格书PDF中文资料

PI2002属于集成电路（IC）的OR控制器理想二极管。由Vicor Corporation制造生产的PI2002OR 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。

描述 Description

The PI2002 Cool-ORingTM solution is a high-speed Active ORing controller IC with a load disconnect feature designed for use with back-to-back Nchannel MOSFETs in redundant power system architectures. The PI2002 Cool-ORing controller enables an extremely low power loss solution with fast dynamic response to fault conditions, critical for high availability systems. The PI2002 controls backto-back MOSFETs providing true bi-directional switch capabilities to protect against both power source and load fault conditions.
