1 / 19 page  Picor Corporation • picorpower.com PI2127 Rev 1.3 Page 1 of 19 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 8.5m Ω internal MOSFET provides very high efficiency and low power loss during steady state operation, while achieving high- speed 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. Features • Integrated High Performance 12A, 8.5m Ω MOSFET • Very small, high density fully-optimized solution with simple PCB layout • Fast dynamic response to power source failures, with 80ns reverse current turn-off delay time • Accurate sensing capability to indicate system fault conditions (-6mV reverse threshold) • Internal charge pump • Active low fault flag output Applications • N+1 Redundant Power Systems • Servers & High End Computing • Telecom Systems • High-side Active ORing Package Information The PI2127 is offered in the following package: • 17-pin 7mm x 8mm thermally enhanced LGA package, achieving <10°C/W RθJ-PCB Typical Application: Figure 1: PI2127 High Side Active ORing Figure 2: PI2127 response time to an input short fault condition |
