Part Number: DRV8848EVM
Other Parts Discussed in Thread: DRV8848,

Hi team,

My customer is interested in the DRV8848 for stepper motor.

Is it possible to set Decay(Coast, Brake) on the DRV8848EVM via GUI? 

Regards,

Yamaguchi

    Hi Yamaguchi-san,

    The DRV8848 can regulate current in mixed decay mode (25% fast / 75% slow) using VREF and Rsense.

    If you want to use Brake or Coast to regulate the current, external circuitry may be needed to measure the current and take action.
