DRV8805: Output Current

Part Number: DRV8805

The DRV8805 can output a current of up to 2-A (single channel on) or 1-A (all channels on) continuous output current (with adequate PCB heatsinking at 25°C).

The unipolar stepper motor is rated as follows:

Rated Current 1A / Phase
Voltage 5.7V
Winding Resistance 5.7Ω / Phase

Will I be able to drive this stepper with the DRV8805 motor driver at it's limit of 1A channel without encountering any thermal or other problems?

Thank you.
