PI2123
Cool-ORing^TM Series
15 Volt, 15 Amp Full-Function Active ORing Solution
Description
The Cool-ORing^TM PI2123 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 PI2123 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 on bus
voltages up to 9.6V. The PI2123 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 PI2123
solutions for high current Active ORing
requirements.
The PI2123, with its 3mΩ 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 PI2123 provides an active low fault flag
output to the system during excessive forward
current, light load, reverse current, over-voltage,
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 external resistor dividers.
