PI2121 Datasheet | Vicor Corporation

Description The Cool-ORing PI2121 is a plete 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 PI2121 Cool-ORing solution is offered in an extremely small, thermally enhanced 5mm x 7mm LGA package and can be used in low voltage (≤ 5Vbus) 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, with its 1.5mΩ 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 PI2121 provides an active low fault flag output to the system during excessive forward current, light load, reverse current, overvoltage, under-voltage and over-temperature fault conditions. A temperature sensing function indicates a fault if the maximum junction temperature exceeds 160°C. The under-voltage and over-voltage .. thresholds are programmable via an external resistor divider.
