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 8.5mΩ 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.
