The Cool-ORing™ PI2121 is a complete full-function Active ORing solution with a high-speed ORing MOSFET controller and a very low on-state resistance (1.5 mΩ) MOSFET designed for use in redundant power system architectures. The PI2121 Cool-ORing solution is offered in an extremely small, thermally enhanced 5 mm x 7 mm LGA package and can be used in low voltage high side Active ORing applications. The PI2121 enables extremely low power loss with fast dynamic response to fault conditions, critical for high availability systems. A master / slave feature allows the paralleling of PI2121 solutions for high current Active ORing requirements. The PI2121 provides an active low fault flag output to the system during excessive forward current, reverse current, light load, overvoltage, undervoltage,and overtemperature fault conditions.
