The DRV2605 device is designed to provide extremely-flexible haptic control of ERM and LRA actuators over a shared I2C-compatible bus. This control relieves the host processor from ever generating pulse-width modulated (PWM) drive signals, saving both costly timer interrupts and hardware pins.

The DRV2605 device provides an extensive integrated library over 100 licensed effects from Immersion for ERM and LRA which eliminates the need to design haptics waveforms.

The DRV2605 device offers a licensed version of the TouchSense 2200 software from Immersion, which includes the 2200 Effects Library, and 2200 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 DRV2605 device also contains a smart-loop architecture, which allows effortless auto resonant drive for LRA as well as feedback-optimized ERM drive. This feedback provides automatic overdrive and braking, which creates a simplified input waveform paradigm as well as reliable motor control and consistent motor performance. The audio-to-haptics mode automatically converts an audio input signal to meaningful haptic effects.

The DRV2605 device features a trinary-modulated output stage, providing greater efficiency than linear-based output drivers. The 9-ball WCSP footprint, flexible operation, and low component count make the DRV2605 device the ideal choice for portable and touch-enabled vibratory and haptic applications.
