Haptic driver for ERM/LRA with waveform library, auto-resonance tracking, & low power consumption

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 designs.
