DRV8845: I find an error from DRV8845 datasheet.

Hello,

Could you please be more specific about the supposed "error" you found in the datasheet?

The decay modes are a way to regulate the motor current. Fast decay, reverses the polarity across the load to allow for quicker current dissipation from the coils. This method is also considered as reverse drive. 

I hope this resolves any issues.

Please respond if there are any other concerns.

David

Hello David,

Item 2 is a fast attenuation mode, but Figure 8-5 shows that Item 2 is a slow attenuation mode.

I draw lines and frames.

Hi David,

I can understand what you mean, but what I want to say is that the datasheet has made an error and he interprets the slow attenuation mode as the fast attenuation mod.

Hi Change,

We will look into the correction.

Thank you for your help.

Best,
