Hi Ivan,
Thanks for your suggestion. I did my own demo board . I tried both (DRV2605 and DRV8601).
DRV2605 raises the cost. It's successful.The only problem is that it will increase the cost. I also can't use a BGA case.
I couldn't get enough information on DRV8601 datasheet. What should be the PWM frequency? I checked the output frequency of the DRV2605. The frequency was quite high. Should the control frequency be high?
10 KHz, 20 KHz etc.?
Is the optimal feed for the LRA I use is Vrms * 1.414 (Vrms 1.8V)?
