I need to control four brushless DC motors of 6V with three hall sensors, my requirements are to have a precise control at low speed, to work on a low supply voltage (5V will be fine) and to be the smaller as possible. Do you have some suggestions of design for me ?
data sheet of the motor :www.micromo.com/.../1509_B_DFF.pdf
Thanks for your help.
I believe the TI reference design that would help you is TIDA-00196 which can be found at http://www.ti.com/tool/TIDA-00196. If you are not able to make this work for your design, more TI reference designs for Hall Effect sensors can be found at https://e2e.ti.com/support/sensor/hall-effect-sensors/f/966/t/355909. If none of these are able to help you, let me know and I'll see what we can do.

Sorry for delayed response. DRV10970 should be perfect fit for your application. DRV10970 works with 3 hall sensor input and can even provide power to hall sensor using 5 V regulated output.
In reply to Krushal:
Fantastic - we have the same need, and I have that particular motor and driver eval board (DRV10970EVM) in front of me. We are having a hard time getting it to work, however - the motor attempts to spin up, but then almost instantly goes into "locked mode." I'm betting at this point that we don't have the correct U/V/W and A/B/C correspondence between the coil outputs, motor drive inputs, and Hall sensor hookups. I don't suppose anybody happens to have solved that what this match-up is?
Also, I am using jumpers J5/7/8 since the Hall sensor outputs are "IC style", but not using any resistors on R17/18/19 ... is that a problem?
