Working Principles

The DRV2605YZFT generates haptic effects by driving an actuator, such as an Eccentric Rotating Mass (ERM) or Linear Resonant Actuator (LRA), with a controlled voltage and current. The haptic effects are created by applying specific waveforms to the actuator, resulting in vibrations or movements that can be felt by the user.

The IC communicates with a microcontroller or other host device through the I2C interface, allowing for real-time control and playback of haptic effects. The built-in library of pre-defined haptic effects provides a convenient starting point for developers, while the waveform sequencer enables the creation of custom haptic waveforms.
