DRV2604L ERM, LRA Haptic Driver Evaluation Kit
The DRV2604L 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 DRV2604LEVM-CT Evaluation Module (EVM) is a complete demo and evaluation platform for the
DRV2604L. 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 DRV2604L.
This document contains instructions to setup and operate the DRV2604LEVM-CT in demo and evaluation
mode.
