Hi team,
Here's an issue from the customer may need your help:
1) The drive chip has a voltage range of 4.5V-45V, assuming two power supplies of 4.5V and 45V, respectively, and the drive capability is infinite. Driving the same motor, 4.5 V supply, is the actual current output larger? Because the power rating of the motor is constant, the driver should not consume significant additional power (there is an efficiency issue, but efficiency should not be low).
2) Also, regarding the motor specific parameters, as long as the current is within the drive chip's index, should be fine for supply voltage selection. Is that correct? It's only related to the drive capability of the power supply. The current that must actually be estimated to account for the drive current capability of the power supply. Is that correct?
Could you help check this case? Thanks.
Best Regards,
Cherry
