Application Information
The PI2121 is designed to replace ORing diodes in
high current, low voltage redundant power
architectures. Replacing a traditional diode with a
PI2121 will result in significant power dissipation
reduction as well as board space reduction,
efficiency improvement and additional protection
features. This section describes in detail the
procedure to follow when designing with the PI2121
Active ORing solution. Two Active ORing design
examples are presented.
Fault Indication:
The FT output pin is an open collector and should
be pulled up to the logic voltage or to the controller
VC via a resistor (10K ? ).
Blanking Timer:
Connect the blanking timer pin (BK) to GND to
program the device for the fastest reverse
comparator response time of 160ns typical. To
increase the blanking time, connect the BK pin to
GND via a resistor to avoid the fault response to
short reverse current pulses. Refer to the plot in the
Functional Description section for resistor values
versus the reverse blanking time.
Auxiliary Power Supply (Vaux):
Vaux is an independent power source required to
supply power to the VC input. The Vaux voltage
should be 5V higher than Vin (redundant power
source output voltage) to fully enhance the internal
MOSFET.
A bias resistor (Rbias) is required if Vaux is higher
than 15V. Rbias should be connected between the
VC pin and Vaux.
Minimize the resistor value for low Vaux voltage
levels to avoid a voltage drop that may reduce the
VC voltage lower than required to drive the gate of
the internal MOSFET.
