Part Number: ULN2803A
Hi
ULN2803A has a diode connected between the output and COM pin are used to suppress surge voltage.
If this diode is ON every 50msec, could it be problem?
I attached the situation to be assumed as follows.
Normally, the voltage at COM is 24V.
① OUTPUT terminal would come 0V to 42V with inrush voltage
② Then, internal diode would be on
③ Finally, COM terminal would come 24V to 42V instantaneously.
The voltage applied to COM is 42V that is less then absolute maximum rating of Vce.
However, I want to confirm if it is problem that the internal diode could be ON periodically (50msec period).
Could you please give us your view?
BestRegards
