Advantages of auto-resonance tracking

Keywords:DRV2603  DRV2604  DRV2605 

The DRV2603, DRV2604 and DRV2605 (DRV260x devices) are linear resonant actuator (LRA) and eccentric rotating mass motor (ERM) haptic drivers with unique features to ease haptic design and system-level challenges. For LRA's, these drivers feature a unique auto-resonance tracking engine which automatically tracks and generates the LRA resonant frequency.

This application report discusses the benefits of auto-resonance tracking in the DRV2605 including vibration strength, response time, and efficiency. These benefits are also applicable to the DRV2603 and DRV2604.
