DRV2605: Improve brake performance

Takahiro Saito
Expert 5315 points
Part Number: DRV2605

Hi team,

Customer is using DRV2605 to drive LRA. They used Strong Click - 100% effect in the waveform library with closed loop setting. The waveform is like below. 

They expected more sharp braking. Is there any way to make more sharp braking? 

Regards,

Saito

    Hello Saito, 

    You can change the FB_BRAKE_FACTOR to a higher value but larger braking gains can lead to less-stable operation so be sure that it is set to as small a factor as possible to achieve the desired braking here. 

    Best Regards,
