DRV2605L ERM and LRA Haptic Driver Evaluation Kit
The DRV2605L 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 DRV2605LEVM-CT evaluation module (EVM) is a complete demo and evaluation platform for the
DRV2605L. The kit includes a microcontroller, linear actuator, eccentric rotating mass motor, sample
waveforms, and capacitive touch buttons, which can completely demonstrate and evaluate the DRV2605L.
This user's guide contains instructions to setup and operate the DRV2605LEVM-CT in demonstration and
evaluation mode.

Page 4: Getting Started
Getting Started The DRV2605L can be used as a demonstration or evaluation tool. When the DRV2605LEVM-CT is powered on for the first time, a demo application automatically starts. To power the board, connect the DRV2605LEVM-CT to an available USB port on your computer using the included mini-USB cable. The demo begins with a board power-up sequence, and then enters the demo effects mode. -
