why isn't anyone using these chips ? can i use them ?

Hello ;

so i am working on a project where i have to control 6 brushed DC motors ; ( 6V motors )
i started this circuit on a breadboard , and made it using 3 L293D integrated circuits .
i then designed my own printed circuit and used 3 DRV8833 integrated circuits instead .
everything worked just fine and i am satisfied with the results . in similar applications , everyone seems to be using
dual-Hbridge ICs like the DRV8833 or the DRV8844 , where to control 6 motors they use 3 ICs .
however , after doing some research i found other ICs like the "DRV8912-Q1"
Here is the datasheet for that : datasheet
this chip has 12 half bridge channels , and its SPI controlled ; which makes it super super convenient for my application , it also has an "automotive" rating .
i am intending to order many of these and start using them instead of using 3 DRV8833 ICs .
however , i am having doubts . everyone seems to be using DRV8833s , even for applications that require the control of up to 6 motors . if they didn't use things like the DRV8912-Q1 that must be for a reason right ?
i just wanted to write this post to know if there's anything that i am missing , and whether or not these new chips
can work for my application .

thank you .

This is probably a more convenient link to the datasheet

I have used the DRV8833 because it is available on a breakout board. I was not aware of the DRV8912-Q1 and I don't know if anyone produces it on a convenient breakout board.

I don't have the capability to make a PCB for a surface mount chip.

Other than that I see no reason why you should not use it. There must be hundreds of motor driver ICs that never feature on this Forum - but that does not mean they are deficient in any way.

If you do decide to use it you might be good enough to tell us about your experience.

Thank you very much for your response Sir ; i am sorry for my choice for the link .
i will make a post about it when i do . and i will share my design so people might benefit from it .
thank you .

Rds ON looks rather high at 1500 mOhms so you can't use many motors with much load simultaneously for an extended period, otherwise it will get hot. It depends on what you are doing with them.

Hello ; Thank you for your attention sir .
its a bionic hand , 6 motors , one for each finger , with an extra motor for the tumb because it has two degrees of freedom . what do you think ?
thank you

Your board design must be able to dissipate the heat using the large belly pad.

Thank you for your attention sir ; yes i am very aware of that , it indeed is very important .
