The PI2001 Cool-ORing® solution is a universal high-speed Active ORing controller IC designed for use with N-channel MOSFETs in redundant power system architectures. The PI2001 controller enables an extremely low power loss solution with fast dynamic response to fault conditions, critical for high availability systems. The PI2001 controls single or parallel MOSFETs to address Active ORing applications protecting against power source failures. The PI2001 can be used in either high-side or low-side Active ORing applications and a master / slave feature allows the paralleling of IC / MOSFET chipsets for high current Active ORing. The PI2001 provides an active low fault flag output to the system during excessive forward current, reverse current, light load, overvoltage, undervoltage and overtemperature fault conditions.
