DRV2605L Haptic Drivers

Texas Instruments DRV2605L Haptic Drivers are a low-voltage haptic driver that includes a haptic-effect library and provides a closed-loop actuator-control system for high-quality haptic feedback for ERM and LRA. This schema helps improve actuator performance in terms of acceleration consistency, start time, and brake time and is accessible through a shared I²C compatible bus or PWM input signal. The Texas Instruments DRV2605L offers a licensed version of TouchSense 2200 software from Immersion that 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.
