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.
