PI2127
Cool-ORing® Series
60 Volt, 12 Amp Full-Function Active ORing Solution
Description
The PI2127 Cool-ORing® 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 PI2127 Cool-ORing
solution is offered in an extremely small, thermally
enhanced 7mm x 8mm LGA package and can be
used in high side, medium voltage Active ORing
applications. The PI2127 enables extremely low
power loss with fast dynamic response to fault
conditions, critical for high availability systems.
The PI2127, with its 8.5mΩ 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 PI2127 provides an active low fault
flag output to the system during reverse current,
excessive forward over-current and UVLO fault
conditions.
Features
• Integrated High Performance 12A, 8.5mΩ
MOSFET

• Accurate sensing capability to indicate system
fault conditions (-6mV reverse threshold)
• Internal charge pump
• Active low fault flag output
Applications
• N+1 Redundant Power Systems
• Servers & High End Computing
• Telecom Systems
• High-side Active ORing

Control Circuitry Return: This pin is the floating return path for the controller circuitry.
Connect this pin via a resistor to the low side return (ground).
Fault Status Output: This open collector pin pulls low to indicate one of the several
potential fault conditions may exist. The Fault pin will pull low after a reverse or forward
FT

fault has been detected with a defined delay time (8μs). In addition, the FT pin will pull
low when the controller input voltage is below the VC under-voltage threshold VS-PG < 7V
(VSUVF). When VS-PG > 7.15V (VSUVR) and 6mV < VSP-SN < 275mV this pin clears (High).
Leave this pin open if unused.

FT Return: This pin is the return (ground) for the open collector fault circuitry. Connect
this pin to logic ground.
Negative Sense Input: Connect SN pin to the trace between D pin (outside of the
PI2127 foot print) and the output load. The polarity of the voltage difference between SP
and SN provides an indication of current flow direction through the MOSFET.
Drain: The Drain of the internal N-channel MOSFET and fault level shift circuit. Connect
this pin to the output load.
Source-The source of the internal N-channel MOSFET and bias for the control circuitry.
Connect this pin to the input power source bus voltage.
Positive Sense Input: Connect SP pin to the trace between S pin (outside of the PI2127
foot print) and the input source. The polarity of the voltage difference between SP and
SN provides an indication of current flow direction through the MOSFET.
