Full-Function Active ORing Solution with Load Disconnect
Pl2122 — Cool-ORing™ Series

Product Resources
 The Cool-ORing™ PI2122 is a complete full-function Active ORing solution with a high-speed ORing MOSFET controller and very low on-state resistance back-to-back configured Dual MOSFETs designed for use in redundant power system architectures where added protection against load fault conditions is required. The back-to-back MOSFET provides a true bi-directional switch capability to disconnect load fault conditions that may induce excessive forward current and device over-temperature. The gate drive is removed from the back-to-back MOSFETs upon detection of such faults and has an auto-retry programmable off-time. The PI2122 Cool-ORing solution is offered in an extremely small, thermally enhanced LGA package and can be used in low voltage (≤5Vbus) high side Active ORing applications. The PI2122 enables extremely low power loss with fast dynamic response, critical for high availability systems. A short circuit detection feature allows user definition of a short condition enabling minimum duty cycle into a short. The over current duty cycle feature provides capacitor selectable duty cycle protection controlling the rate of temperature increase during a load fault condition.
