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 3m

Ω 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.
