The PI2127 Cool-ORing® is a complete full-function Active ORing solution with a high-speed ORing MOSFET controller and a very low on-state resistance MOSFET designed for use in redundant power system architectures. The PI2127 Cool-ORing solution is offered in an extremely small, thermally enhanced 7mm x 8mm LGA package and can be used in high side, medium voltage Active ORing applications. The PI2127 enables extremely low power loss with fast dynamic response to fault conditions, critical for high availability systems.

The PI2127, with its 8.5mΩ internal MOSFET provides very high efficiency and low power loss during steady state operation, while achieving highspeed turn-off of the internal MOSFET during input power source fault conditions that cause reverse current flow. The PI2127 provides an active low fault flag output to the system during reverse current, excessive forward over-current and UVLO fault conditions.
