Cool-ORing Series

12Amp Active ORing Solution With Load Disconnect

Description

Features

The Cool-ORing PI2122 is a complete full-function

Active ORing solution with a high-speed ORing

•

Integrated High Performance 12A, 6mΩ back-to-

back MOSFET

MOSFET controller and

a very low on-state

Very-small, high density fully-optimized solution

providing simple PCB layout.

Fast Dynamic Response, with 140ns reverse &

170ns forward over-current turn-off delay time

Accurate sensing capability to indicate system

fault conditions

Programmable under & over-voltage functions

Over temperature shutdown

Programmable over-current off time

Programmable short circuit load detection

Active low fault flag output

resistance Dual MOSFETs designed for use in

redundant power system architectures. 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 to fault

conditions, critical for high availability systems. The

PI2122 provide true bi-directional switch capabilities

to protect against both power source and load fault

conditions.

•

A load short circuit detection feature allows user

definition of a short condition enabling minimum duty

cycle into a short. The PI2122 has the added benefit

of being able to protect against output load fault

conditions that may induce excessive forward

current and device over-temperature by turning off

the back-to-back MOSFETs with an auto-retry

programmable off-time. The back-to-back MOSFETs

drain-to-drain voltage is monitored to detect normal

forward, excessive forward, light load and reverse

current flow. The status is reported via an active low

fault flag output. A temperature sensing function

turns off the MOSFETs and indicates a fault if the

controller junction temperature exceeds 145°C.

Applications

•

N+1 Redundant Power Systems

Servers & High End Computing

High-side Active ORing

High current Active ORing ( ≤ 5Vbus)

MicroTCA

Package

•

5mm x 7mm 17-pin Thermally Enhanced LGA

Package
