Functional Description
Snubber capacitors 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
To indicate a fault exists when it is on
Bypass diodes
Constant Current bias circuit Zener
Constant Current bias circuit Transistor
Constant Current bias circuit, bias resistors
Constant Current bias circuit, sets the current limiting
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
