PI2003集成电路（IC）的OR控制器理想二极管规格书PDF中文资料

PI2003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PI2003OR 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 PI2003 Cool-ORingTM solution is a universal high-speed Active ORing controller IC designed for use with N-channel MOSFETs and is optimized for - 48V redundant power system architectures. The PI2003 Cool-ORing controller enables an extremely low power loss solution with fast dynamic response to input power fault conditions, critical for high availability systems. The PI2003 controls single or parallel MOSFETs to address Active ORing applications protecting against power source failures. The PI2003 is optimized for -48V low-side Active ORing applications. An internal VC shunt regulator enables biasing of the controller directly from -48V(GND).
