Dear colleagues,
I am planning to use one of them to provide bidirectional control to two motors (drive currents less than 1A @ 12VDC), so they can rotate in the two ways. I've gone over two options by TI: DRV8844 and SN754410 (datasheets linked).
The point is that despite technical specifications describe both ICs as quadrupole half-H bridges, I'm not sure if they implement the same circuitry at component level.
SN754410 datasheet is more complete on schematics, from which I can understand they implement TTL logic to drive the current using Darlington pairs and single transistors. On the other hand, DRV8844 datasheets are not generous in schematics, so I cannot check if they use the same logic or, but on the contrary, they implement some other technology.
¿Could you give me a light on this issue?
Thank you very much in advance.
