Thank you!That information would be very helpful in the datasheet.
View ArticleRE: DRV8871: Is there any equivalent IC but for higher currend needs?
But I need higher, not lower currents. So, what should I do? Do I boost the DRV8871 output to my needed values or is there any IC that supplies my motor properly?

View ArticleRE: DRV110: DRV110 current dropout between peak and hold values
Hello Kevin,This is strange. I haven't seen this kind of behavior before. When switching from Peak to Hold it is common for the PWM cycle to reach the minimum 7.5%, but it will continue to PWM.Could...
