Functional Description
Snubber to reduce voltage ringing when the device turns off
Add the capacitors if a long harnesses are used to connect the power source or load to the
board.
VC Bypass Capacitor
Output (Load) Capacitor
Output (Load) Capacitor, this capacitor can be installed if instead of C7 if the user requires a
ceramic load capacitor, 1812 package can accommodate a high ceramic capacitors value at
25V rating.
To indicate a fault exists when it is on
ORing switch
Gate resistor, optional to slow gate turn off time, higher value resistor will reduce gate pull
down peak current
VC bias resistor
Optional to use PI2007 external VC bias voltage, removing R3 and R4 when external bias
voltage is used.
Optional to use PI2007 internal VC bias resistor (VR) by placing 0Ω resistor and removing R3
and R4
LED current limit resistor, selected to operate at 3.3V and 5.0V logic voltage. Replace R15
and R16 with the proper resistor value for different logic voltage.
Cool ORing Controller
