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, and 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 be used to completely demonstrate and evaluate the DRV2605.
