The PI2003 Cool-ORing™ 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 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 low-side –48V Active ORing applications. An internal VC shunt regulator enables biasing of the controller directly from –48 V (GND).
