Hello,

We have several evaluation modules, EVMs, available on the web: DRV2605EVM-CT, DRV2625EVM-CT, DRV2625EVM-MINI. The user guides to these devices have PCB schematics and layouts at the end of the guides. The DRV2625 is our newest device with the most advanced features. The DRV8601 isn't the best choice for driving LRAs because it does not track the resonance frequency.

dear Kelly Griffin

Sorry，i did not find any documents to introduce the "DRV2605EVM-CT ERM/LRA Haptic Driver Evaluation", i can only find DRV2605' datasheet . and i just want to let my LRA vibrate(not rotate).

Thanks!

Hi,

In the DRV2605EVM-CT product page, under technical documents, you can find the datasheet and applications notes regarding this device (EVM). It includes both an ERM and a LRA, so you can test them both.

Regards,

Leo
