The DRV10964 EVM is an evaluation platform for the DRV10964 three-phase brushless DC motor driver. The EVM includes a TLC555 timer configured to supply a PWM to the DRV10964 and potentiometer to adjust the speed of the motor by varying the duty cycle of the PWM. -
Page 3: Drv10964 On-Board Connections
DRV10964 On-Board Connections Power Input The DRV10964 requires an external power supply (2.1 V to 5.5 V) to operate. Connector J1 provides the required interface for the external power supply. The pin assignment of terminal P1 is as follows: Table 1. DRV10964... -

For more information on the PWM input required by the DRV10964, refer to the datasheet (SLDS227). Test Points Test points are provided and labeled according to the inputs and outputs of the DRV10964 motor driver (see Table Table 5. -
Page 7: Tune Open To Close Loop Handoff Threshold
Tune Open to Close Loop Handoff Threshold The DRV10964 has the option of changing open to close loop handoff threshold by configuring the CONFIG pin. If there is an issue with the motor starting up, TI recommends changing the open to close loop handoff threshold. - Page 8 In such cases, it is recommended to increase the open to close loop handoff threshold. Figure 6 shows the phase current for properly tuned open to close loop handoff threshold.
