DRV8711: Auto-mixed decay mode

Hirotaka Matsumoto

Part Number: DRV8711

Hi all

Would you mind if we ask DRV8711?

There is the description "Auto-mixed decay mode".
What is the difference between "Auto-mixed decay mode" and "Auto Tune"?
Does "Auto-mixed decay mode" mean mixed decay mode?

Kind regards,

Hirotaka Matsumoto

    Hi Matsumoto-san,

    Auto-mixed decay is an early version of AutoTune. Auto-mixed decay is more complicated because the blanking time, adaptive blanking time, decay time, and PWM off time is adjustable via registers.

    Auto-mixed decay and AutoTune both use mixed decay modes. AutoTune has an advance algorithm to adjust the percentages of slow/fast decay.
