PI2003 Datasheet | Vicor Corporation

Description 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 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). The gate drive output turns the MOSFET on during normal steady state operation, while achieving highspeed turn-off during input power source fault conditions, that cause reverse current flow, with auto-reset once the fault clears. The MOSFET drain-to-source voltage is monitored to detect normal forward, excessive forward, light load and reverse current flow. The PI2003 provides an active low fault flag output to the system during excessive forward current, reverse current and light load. ..
