The DRV2605L-Q1 device is an automotive haptic driver that includes a haptic-effect library and provides a closed-loop actuator-control system for high-quality tactile 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 DRV2605L-Q1 device offers a licensed version of TouchSense 2200 software from Immersion which eliminates the requirement 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 DRV2605L-Q1 device allows simple auto-resonant drive for the LRA as well as feedback-optimized ERM drive allowing for automatic overdrive and braking. The smart-loop architecture creates a simplified input waveform interface as well as reliable motor control and consistent motor performance. The DRV2605L-Q1 also allows for open-loop driving through the use of internally-generated PWM. Additionally, the audio-to-vibe mode automatically converts an audio input signal to meaningful tactile effects.
