DRV2605 - Haptic Driver

General Description

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.

Key Features

  • 1 Flexible Haptic/Vibra Driver.
  • LRA (Linear Resonance Actuator).
  • ERM (Eccentric Rotating Mass).
  • I2C Controlled Digital Playback Engine.
  • Real-Time Playback Mode via I2C.
  • Smart Loop Architecture(1).
  • Automatic Overdrive/Braking (ERM/LRA).
  • Automatic Resonance Tracking (LRA).
  • Automatic Actuator Diagnostic (ERM/LRA).
  • Automatic Level Calibration (ERM/LRA).
  • Licensed Immersion™ TouchSense® 2200 features:.
