UAA4003DP Chip Alternative

tsteg · ‎2024-03-17

I am looking for a alternative chip to replace an obsolete part.

The part is a ST UAA4003DP This a 16 pin chip used in a DC motor drive to control the motor speed.

I can't find any information on this other than the fact that it is obsolete..

I did find a data sheet for a UAA4000 chip, but it is for a remote control transmitter.

Welcome @tsteg, to the community!

In fact, this ancient part has been discontinued - after all, it was launched in 1988. At least I don't know of any alternative that is even similar. Unfortunately, the documentation for discontinued devices is being destroyed, but perhaps the data sheet I found here will help you.

I'm extremely sorry, but that's all I can help you with.

Good luck!

Found the same.

Whatever board/design this is on, you're likely going to have to redesign, and create an alternative
