SN754410 alternative anynone?

Hello group.

I have been looking for an SN754410 alternative without success. I
need a device with similar electrical characteristics (two coil
drivers, 1A drive per channel, 4.5-30V input), but in a SMT
(reflowable) package. The most close candidate I have been able to find
is the Allegro 3964, but it only does 800mA, is not that cheap and
difficult to source. Other technology than bipolar (eg DMOS) may do.

Thanks in advance. Cheers.

I went to TI and did a parametric search - according to the results,
there are 3 Quad Half-H drivers, and the L293 is available in a 28SO
PowerPad, but this does not have the clamp diodes. If you put on
external clamps, you could use that, perhaps. Budgetary pricing $3.80 /
1k qtys.

Here's the heading:

The L293 may be found here

That one is also in my list. I was avoiding adding external diodes,
but it seems it will be the best choice considering price and
availability.

Thanks again. Cheers.

You might check out parts from STMicro and Vishay, available through
mouser.com, namely the L620x and SI998x families ....
