Part Number: ULN2803A
Hi
I want to drive solenoids with ULN2803A. I am planning to use 2 parallel wired ULN2803A. Is there any protection against high current? Solenoids that I use are draining 1.3A at 24V but 1A is also enough them to operate. Could…
Part Number: ULN2803A Hi,
Good day. I hope you are well. Our customer wants to use the ULN2803A ans they need the exact Logic voltage levels. Can you please help us provide logic voltage levels (VIH,VIL,VOH,VOL) for ULN2803A? Thank you for your help on this…
Part Number: ULN2803A Hi Expert,
I am using ULN2803A in my PLC DO board, and we have produced a lot of PCB boards.
However, recently we find ULN2803A broken(package burned out) in several boards, but the same board will work well again when we replace…

Part Number: ULN2803A Hello guys.
One of my customers is evaluating ULN2803A for their new products.
They have a few questions as the follows. Could you please give me your reply?
Q1. The ULN2803A drives a magnetic buzzer with self oscillation circuit…
Part Number: ULN2803A In one of our new design we are using ULN2803A for driving Relay. Circuit is as given in attachment.
Please confirm whether PULL DOWN is required an Pin1 of ULN2803. And also confirm whether schematic is correct.
Thanks in advance…
Part Number: ULN2803A My ULN2803A connects a resistive load and an inductive load with differenent channel. The two loads are powered by the same 48V voltage source, which is provided by an adapter. The COM pin is also connected to the 48V power. I do…
Hi Andy,
Excuse me for the delay. I did a last set of measurments and it appears that with the 91WK28B batch (the one with which I discovered the problem) the transistor starts to conduct above 1.47V. And it's 1.52V with the 82ZD6V4 batch. Moreover, as…
