Much thanks, Soeren
-I'm yet to select the two DC motors (had two, but found they were different RPM's
Get some fast diodes and be on the safe side. The ESD protection diodes may do it, but you have no way of knowing and adding some fast recovery diodes is a fairly cheap way of being sure.
Sounds like it may be the easiest (and smartest) solution, yes
And verified. (as below)
On using the SN754410: Some people use the SN754410 motor driver chip because it is pin-compatible, has output diodes and can provide 1A per motor, 2A peak. After careful reading of the datasheet and discussion with TI tech support and power engineers it appears that the output diodes were designed for ESD protection only and that using them as kickback-protection is a hack and not guaranteed for performance.
Now... I'm not sure what specifications I require the diodes to have.
Is this based on how much Amperage the motor/s need only?
I know the motors I choose will draw less than 1A (each).
(the MD chip I'm planning to use has 1-A Output-Current Capability Per Driver)
If it's amperage only, I'm assuming something like the UF4007
or the FR157
(I can get the FR157's cheaper.)
Any help or nudge in the right direction would be greatly appreciated
