DRV8835: reduce motor starting current

Part Number:DRV8835

Hi,

DRV8835 is to reduce motor starting current.

As a measure to reduce the motor starting current,
 we are considering changing the VM voltage (For example VM=3.0V → 7.0V).

1. Is this a problem as how to use DRV8835?

2. I can imagine that Ron of the built-in FET changes,
    Is it possible to think that when the motor starts up, when the VM is low(For example VM=3.0V),
    the current increases?

3. In addition to changing the VM, what is the best way to reduce the motor startup current?

best regards
