1 / 15 page  Picor Corporation • picorpower.com PI2126 Rev 1.1 Page 1 of 15 PI2126 Series 30 Volt, 12 Amp Full-Function Active ORing Solution Description The PI2126 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 12V Bus redundant power system architectures. The PI2126 Cool-ORing solution is offered in an extremely small, thermally enhanced 5mm x 7mm LGA package and can be used in high side Active ORing applications. The PI2126 enables extremely low power loss with fast dynamic response to fault conditions, critical for high availability systems. The PI2126, with its 4.5mΩ internal MOSFET provides very high efficiency and low power loss during steady state operation. The PI2126 monitors the current direction in the MOSFET and will respond very fast to a reverse current due to input power source fault condition to prevent undesired high current build-up in the system. The PI2126 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, 4.5mΩ MOSFET Very small, high density fully-optimized solution with simple PCB layout Fast dynamic response to power source failures, with 90ns reverse current turn-off delay time Accurate sensing capability to indicate system fault conditions (-6mV reverse threshold) Internal charge pump Fault Status output Applications N+1 Redundant Power Systems Servers & High End Computing Telecom Systems High-side Active ORing Package Information The PI2126 is offered in the following package: 25-pin 5mm x 7mm thermally enhanced LGA package, achieving <11°C/W RθJ-PCB Typical Application: Figure 1: PI2126 High Side Active ORing Figure 2: PI2126 response time to an input short fault condition VR PI2126 Vin1 S D Vin2 FT FT SP SN VC VR PI2126 S D FT FT SP SN VC Applied Input Short Input Current V(S) (Input) V(D) Redundant Bus 90ns Reverse detection MOSFET Turn Off Time 0A 0V Normal operation Reverse Current EOL |
