Package: DSBGA (9) , VSSOP (10) Type

Manufacturer: Texas Instruments


DRV2605L datasheet



The DRV2605L device offers a licensed version of TouchSense 2200 software from Immersion which eliminates the need to design haptic waveforms because the software includes over 100 licensed effects (6 ERM libraries and 1 LRA library) and audio-to-vibe features.

Additionally, the real-time playback mode allows the host processor to bypass the library playback engine and play waveforms directly from the host through I2C.

The smart-loop architecture inside the device allows simple auto-resonant drive for the LRA as well as feedback-optimized ERM drive allowing for automatic overdrive and braking. This architecture creates a simplified input waveform interface as well as reliable motor control and consistent motor performance. The device also features automatic transition to an open-loop system in the event that an LRA actuator is not generating a valid back-EMF voltage. When the LRA generates a valid back-EMF voltage, the device automatically synchronizes with the LRA.
