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

|
 |
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. |
