Haptic Driver for ERM and LRA with Built-In Library and Smart Loop Architecture

Check for Samples: DRV2605

FEATURES

DESCRIPTION

The DRV2605 is designed to give extremely flexible

haptic control of ERM and LRA actuators over a

shared I²C compatible bus. This relieves the host

processor from ever generating pulse-width

modulated (PWM) drive signals, saving both costly

timer interrupts and hardware pins.

•

Flexible Haptic/Vibra Driver

–

LRA (Linear Resonance Actuator)

ERM (Eccentric Rotating Mass)

•

I²C Controlled Digital Playback Engine

–

Royalty-Free Integrated Immersion Library

Real-Time Playback Mode via I²C

The DRV2605 gives royalty-free access to an

extensive integrated library (100+ effects) from

Immersion for ERM and LRA. This eliminates the

need to design haptic waveforms.

Smart Loop Architecture⁽¹⁾

–

Automatic Overdrive/Braking (ERM/LRA)

Automatic Resonance Tracking (LRA)

Automatic Actuator Diagnostic (ERM/LRA)

Automatic Level Calibration (ERM/LRA)

Additionally, the real-time playback mode allows the

host processor to bypass the library playback engine

and play waveforms directly from the host via I2C.

The DRV2605 also contains

smart loop

•

Audio To Haptics Mode

architecture, which allows effortless auto resonant

drive for LRA as well as feedback-optimized ERM

drive. This feedback gives 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.

Optional PWM Input with 0% to 100% Duty

Cycle Control Range

•

Optional Analog Input Control

Optional Hardware Trigger Pin

Efficient Output Drive

Fast Start Up Time

Constant Acceleration Over Supply Voltage

1.8 V Compatible, VDD Tolerant Digital Pins

Available in a 9-Ball, 0.5 mm Pitch WCSP

Patent pending control algorithm

The DRV2605 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 the ideal choice for portable and touch-

enabled vibratory and haptic applications.
