DRV2605EVM-CT ERM and LRA Haptic Driver Evaluation
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.

  • Page 4: Getting Started

    Getting Started The DRV2605 can be used as a demonstration or evaluation tool. When the DRV2605EVM-CT is powered on for the first time, a demo application automatically starts. To power the board, connect the DRV2605EVM-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.
