3 Description
The DRV2625 device is a haptic driver that relies on
a proprietary closed-loop architecture to deliver
sharp, strong, and consistent haptic effects while
optimizing power consumption.
The internal library and loopable waveform
sequencer, together with the automatic overdrive and
braking simplifies the process of generating crisp and
optimum haptic effects, reducing the burden imposed
into the processing unit.
The DRV2625 device features an automatic go-to-
standby state and a battery preservation function to
help reduce power consumption without user
intervention. The NRST pin allows for a full shutdown
state for additional power savings.
The waveform shape selection allows for sine-wave
and square-wave drive to customize the haptic feel
as well as the audible performance. Off-resonance
driving with automatic braking simplifies the
implementation of non-resonant haptic solutions.
