DRV2603 Haptic Driver

Texas Instruments' haptic driver with auto-resonance tracking for Linear Resonance Actuators (LRA) and optimized drive for Eccentric Rotating Mass (ERM) motors

Texas Instruments DRV2603 Haptic Driver Texas Instruments' DRV2603 is a haptic driver designed to control 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, simplified control signaling, quick device startup, and auto-resonance frequency tracking.

The DRV2603EVM-CT evaluation module (EVM) is a complete demo and evaluation platform for the DRV2603. The kit includes a microcontroller, linear actuator, eccentric rotating mass motor, samples waveforms, and capacitive touch buttons which can be used to completely demonstrate and evaluate the DRV2603.
