Brian,

The DRV8701, DRV8702-Q1, DRV8702D-Q1, DRV8703-Q1, and DRV8703D-Q1 are our closest devices. Speed control and hall-sensor feedback may need to be controlled by external circuitry. We do not integrate those features in these devices.

TIDA-00875 gives an example for driving this kind of motor: www.ti.com/.../TIDA-00875
