 PI2127 Cool-ORing® Series 60 Volt, 12 Amp Full-Function Active ORing Solution 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 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.

Leave this pin open if unused. GND 6 FT Return: This pin is the return (ground) for the open collector fault circuitry. Connect this pin to logic ground. SN 8 Negative Sense Input: Connect SN pin to the trace between D pin (outside of the PI2127 foot print) and the output load. The polarity of the voltage difference between SP and SN provides an indication of current flow direction through the MOSFET. D 9, 10, 11, 17 Drain: The Drain of the internal N-channel MOSFET and fault level shift circuit. Connect this pin to the output load. S 12, 13, 14 16 Source-The source of the internal N-channel MOSFET and bias for the control circuitry. Connect this pin to the input power source bus voltage. SP 15 Pin Name Description Not Connected: Leave pins floating. Positive Sense Input: Connect SP pin to the trace between S pin (outside of the PI2127 foot print) and the input source. The polarity of the voltage difference between SP and SN provides an indication of current flow direction through the MOSFET.
