    Hi Yaita-san,

    We will have to investigate. Can you provide more information about the application?

    Will the motor run at 2A continuously?
    What is the ambient temperature?

    Hi Rick-san,

    Thank you for your quick response.
    I will put the reply as the folllowing.

    Will the motor run at 2A continuously?
    ->My customer drives a unipolar stepper motor for 2-phase full-step.
     The requirement is 1.5A continuously and 2A peak per channel simultaneously when two channels on.

    What is the ambient temperature?
    ->up to Ta=80℃
