DRV2605EVM-CT ERM and LRA Haptic Driver Evaluation

Kit

The DRV2605 is a haptic driver designed for linear resonant actuators (LRA) and eccentric rotating mass
(ERM) motors. It provides many features, which help eliminate the design complexities of haptic motor
control including:

•

Reduced solution size

•

High-efficiency output drive

•

Closed-loop motor control

•

Quick device startup

•

Embedded waveform library

•

Auto-resonance frequency tracking

The DRV2605EVM-CT evaluation module (EVM) is a complete demo and evaluation platform for the
DRV2605. The kit includes a microcontroller, linear actuator, eccentric rotating mass motor, sample
waveforms, and capacitive touch buttons, which can completely demonstrate and evaluate the DRV2605.

This user's guide contains instructions to setup and operate the DRV2605EVM-CT in demonstration and
evaluation mode.

Evaluation Kit Contents:

•

DRV2605EVM-CT demo and evaluation board

•
