1 DRV2625 ERM, LRA Haptic Driver Evaluation Kit

The DRV2625 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, memory for waveform storage, and auto-resonance frequency tracking.

The DRV2625EVM-CT Evaluation Module (EVM) is a complete demo and evaluation platform for the DRV2625. The kit includes a microcontroller, linear actuator, eccentric rotating mass motor, and capacitive touch buttons which can be used to completely demonstrate and evaluate the DRV2625.

This document contains instructions to setup and operate the DRV2625EVM-CT in demo and evaluation mode.
