Ref. Designator Value/Part NO. Functional Description
C1, C2, C3, C4 Not Installed
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.
C5, C6 1uF VC Bypass Capacitor
C7 22uF Output (Load) Capacitor
C8 Not Installed
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.
D1, D2 LTST-C191CKT To indicate a fault exists when it is on
Q1, Q2 SI4630DY-T1-GE3 ORing switch
R1, R2 0Ω
Gate resistor, optional to slow gate turn off time, higher value resistor will reduce gate pull
down peak current
R3, R4 430Ω VC bias resistor
R5, R6, Not Installed
Optional to use PI2007 external VC bias voltage, removing R3 and R4 when external bias
voltage is used.
R7, R8 Not Installed
Optional to use PI2007 internal VC bias resistor (VR) by placing 0Ω resistor and removing R3
and R4
R15, R16 1.5K
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.
