3 Description
The DRV2605L-Q1 device is an automotive haptic
driver that includes a haptic-effect library and
provides a closed-loop actuator-control system for
high-quality tactile feedback for ERM and LRA. This
schema helps improve actuator performance in terms
of acceleration consistency, start time, and brake time
and is accessible through a shared I2C compatible
bus or PWM input signal.
The DRV2605L-Q1 device offers a licensed version
of TouchSense 2200 software from Immersion which
eliminates the requirement to design haptic
waveforms because the software includes over 100
licensed effects (6 ERM libraries and 1 LRA library)
and audio-to-vibe features.
Additionally, the real-time playback mode allows the
host processor to bypass the library playback engine
and play waveforms directly from the host through
I2C.
The smart-loop architecture inside the DRV2605L-Q1
device allows simple auto-resonant drive for the LRA
as well as feedback-optimized ERM drive allowing for
automatic overdrive and braking. The smart-loop
architecture creates a simplified input waveform
interface as well as reliable motor control and
consistent motor performance. The DRV2605L-Q1
also allows for open-loop driving through the use of
internally-generated PWM. Additionally, the audio-to-
vibe mode automatically converts an audio input
signal to meaningful tactile effects.

software, see the Legal Notice section.
