Other Parts Discussed in Thread: DRV10866, , TPS22860, DRV10866EVM, , DRV10963
DRV10866 has this feature. It is not clear to me from reading the datasheet that the DRV10964 has this feature. IOW, does the PWM pin need to be pulsed high and low at some duty cycle less than 100% and some frequency less than 100khz (electrical characteristic FPWM in datasheet.)
I have tested this feature on the DRV10964, holding PWM high, and it does not appear to work, but there could be other reasons such as I chose a wrong motor or I have configured the open loop wrong. I am testing using the Mikroe "Brushless 2 Click" breakout board and a Nidec 10S BLDC motor ( a CD spindle motor, 12 ohm, 12k rpm, 12V). When holding PWM high, a DRV10866 will drive the motor at 5V but the DRV10964 doesn't. The test setup is also missing a bypass capacitor on the DRV10964.
