Application Information:
The PI2007 is designed to replace ORing diodes in
high current redundant power architectures.
Replacing a traditional diode with a PI2007 controller
IC and a low on-state resistance N-channel MOSFET
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 PI2007 Active ORing controller and
N-Channel MOSFETs. Two different Active ORing
design examples are presented.
VC Bias:
The PI2007 has a separate input (VC) that provides
power to the control circuitry, the charge pump and
the gate driver. An internal regulator clamps the VC
voltage (V VC-SGND ) to 11.7V. A bypass ceramic
capacitor (C VC = 1μF) has to be connected between
VC and SGND to hold V VC-SGND steady. Also, the Gate
turn off return (PGND) should be connected to SGND
at the C VC termination to keep SGND noise free when
the Gate is turned off in response to a fault.
In 12V system applications, where the input voltage
(Vin) is between 10V and 14V, connect the VR pin to
Vin and connect SGND and PGND to the Vin return.
A 420Ω internal resistor is connected between the VR
pin and the VC pin.
In high voltage applications, above 14V, a bias
resistor (R PG ) and low current low forward voltage
drop Schottky diode are required. Connect one
terminal of R PG to the SGND and PGND and the other
terminal to ground (Vin return). The Schottky diode
anode will be connected to the SGND pin and its
cathode connected at the VC pin. See typical
application drawings on page 1.
Recommended Schottky:
