Cool-ORing^® Series
Universal High Side Active ORing Controller IC
Description
The PI2007 Cool-ORing^® solution is a universal
high-speed Active ORing controller IC designed for
use with N-channel MOSFETs in redundant power
system architectures. The PI2007 Cool-ORing
controller enables an extremely low power loss
solution with fast dynamic response to fault
conditions, critical for high availability systems. The
PI2007 controls single or parallel MOSFETs to
address Active ORing applications protecting
against power source failures. The PI2007 has an
internal charge pump enabling an ideal solution in
12V or 36-75V bus high-side Active ORing
applications.
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 causes reverse current flow. The
controller auto-resets once the fault clears. The
MOSFET drain-to-source voltage is monitored to
detect reverse current flow. The PI2007 has an
internal charge pump to drive the gate of a high side
N-Channel MOSFET above the VC input. There is
an internal shunt regulator at the VC input for high
voltage applications.
