DRV2605 Haptic Motor Driver
The DRV2605 haptic motor driver component allows the user to configure and play custom or preconfigured haptic feedback sequences via a serial interface such as I2C. It supports directly driving ECM (eccentric rotating mass) and LRA (linear resonant actuator) type haptic motors. It also supports fully custom waveforms (e.g. via using the audio, pwm / analog functions) as well as a preset library of 123 different haptic waveforms which can be played in sequences of up to 8 waveforms.
