PI2001

Cool-ORingTM Series

Universal Active ORing Controller IC

Description

The PI2001 Cool-ORingTM solution is a universal

high-speed Active ORing controller IC designed for

use with N-channel MOSFETs in redundant power

system architectures. The PI2001 Cool-ORing

controller enables an extremely low power loss

solution with fast dynamic response to fault

conditions, critical for high availability systems. The

PI2001 controls single or parallel MOSFETs to

address Active ORing applications protecting

against power source failures. The PI2001 can be

used in either high-side or low-side Active ORing

applications and a master/slave feature allows the

paralleling of IC/MOSFET chipsets for high current

Active ORing.

The gate drive output turns the MOSFET on in

normal steady state operation, while achieving high-

speed turn-off during input power source fault

conditions, that cause reverse current flow, with

auto-reset once the fault clears. The MOSFET

drain-to-source voltage is monitored to detect

normal forward, excessive forward, light load and

reverse current flow. The PI2001 provides an active

low fault flag output to the system during excessive

forward current, reverse current, light load, over-

voltage, under-voltage and over-temperature fault

conditions. There is an internal shunt regulator at

the VC input for high voltage applications and the

under-voltage and over-voltage thresholds are

programmable via external resistor dividers.
