3 Description
The DRV2605L device is a low-voltage 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.
1
The DRV2605L 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
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 device
also features automatic transition to an open-loop
system in the event that an LRA actuator is not
generating a valid back-EMF voltage. When the LRA
generates a valid back-EMF voltage, the DRV2605L
device automatically synchronizes with the LRA. The
DRV2605L 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.
