The PI2002 Cool-ORing™ solution is a high-speed Active ORing controller IC with a load disconnect feature designed for use with back-to-back N-channel MOSFETs in redundant power system architectures. The PI2002 can also be used with a single MOSFET as a low side disconnect switch. 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 back-to-back MOSFETs providing true bi-directional switch capabilities to protect against both power source and load fault conditions.
