Cool-ORing® Series 60 Volt, 12 Amp Full-Function Active ORing Solution, PI2127 PI2127 Features Integrated high performance 12 A, 8.5 mΩ MOSFET PI2127 Very small, high density fully-optimized solution with simple PCB layout Fast dynamic response to power source failures, with 80 ns reverse current turn-off delay time Accurate sensing capability to indicate system fault conditions (-6 mV reverse threshold) Internal charge pump 7 mm x 8 mm 17-Pin Thermally Enhanced LGA Active low fault flag output Low thermal impedance RΘJ-PCB < 10°C / W Product Description 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 7 mm x 8 mm 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 provides an active low fault flag output to the system during reverse current, excessive forward over-current and UVLO fault conditions. The PI2127, with its 8.5 mΩ 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.
