The DRV2605L device is a low-voltagehaptic driver thatincludes a haptic-effect library and provides a closed-loopactuator-control system for high-quality tactile feedback for ERM and LRA. This schema helpsimprove actuator performance in terms of acceleration consistency, start time, and brake time andis accessible through a shared I2C compatible bus or PWM input signal.

The DRV2605L device offers a licensedversion of TouchSense 2200 software from Immersion which eliminates the requirement to designhaptic waveforms because the software includes over 100 licensed effects (6 ERM libraries and 1 LRAlibrary) and audio-to-vibe features.

Additionally, the real-time playback modeallows the host processor to bypass the library playback engine and play waveforms directly from the hostthrough I2C.

The smart-loop architecture inside the DRV2605L device allows simpleauto-resonant drive for the LRA as well as feedback-optimized ERM drive allowing for automaticoverdrive and braking. The smart-loop architecture creates a simplified input waveform interface aswell as reliable motor control and consistent motor performance.The DRV2605L device also featuresautomatic transition to an open-loop system in the event that an LRA actuator is not generating avalid back-EMF voltage. When the LRA generates a valid back-EMF voltage, theDRV2605L device automatically synchronizes with the LRA. TheDRV2605L also allows for open-loop driving through the use ofinternally-generated PWM. Additionally, the audio-to-vibe modeautomatically converts an audio input signal to meaningful tactile effects.
