Topic: ULN2064B relay driver (Read 875 times) previous topic - next topic

Hi
I am planning to use ULN2064B ic in my project. when i checkedthe datasheet, it is mentioned that each dqrlington provides about 1.5A at a breakdown voltage of 50v. Does this mean that I have to use 50v supply to get that much of current. How much can i get at 12v?

No, 50V is the maximum rating

1.5A see the graph, i/p current controls o/p current

Have you looked at ULN2803 (500ma for each) you get 8 drivers, can be put in parallel, with common snubbing diodes.
The way you have it in your schematic isn't the same as how you have it wired up!

You can get 1.5A at any voltage.

I used uln 2003. The ic burned off when i used it. i need more than 500mA.

What "did you say" you were driving?
