Product 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 highspeed 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.
