DRV2605L Multi-Driver ERM, LRA Haptic Driver Evaluation
1
Introduction
The DRV2605L device is a haptic driver designed for linear resonant actuators (LRA) and eccentric
rotating mass (ERM) motors. The device has many features that 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 DRV2605LEVM-MD evaluation module (EVM) is an evaluation platform for the DRV2605LDGS. The
kit includes an MSP430F5510 microcontroller (MCU), terminal output support for up tight LRAs or ERMs,
sample waveforms provided by Immersion, and capacitive touch buttons which demonstrate the
capabilities of the DRV2605L.
This user's guide contains instructions for setting up and operating the DRV2605LEVM-MD.
