3 Description
The DRV2604L device is a low-voltage haptic driver
that 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 I
2
C
compatible bus or PWM input signal.
The DRV2604L device includes enough integrated
RAM to allow the user to pre-load over 100
customized smart-loop architecture waveforms.
These waveforms can be instantly played back
through I
2
C or optionally triggered through a
hardware trigger terminal.
Additionally, the real-time playback mode allows the
host processor to bypass the memory playback
engine and play waveforms directly from the host
through I
2
C.
The smart-loop architecture inside the DRV2604L
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 DRV2604L 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 DRV2604L
device automatically synchronizes with the LRA. The
DRV2604L also allows for open-loop driving through
the use of internally-generated PWM.
