DRV2625EVM-MINI: Haptic ERM/LRA Driver, 2.7 ~ 5.5V in

The DRV2625EVM-MINI is a small, break-out board for the DRV2625 ERM/LRA Haptics driver. The board can be used for quickly integrating the DRV2625 into any new or existing system. The DRV2625 is an ultra-low power Haptic driver with integrated waveform library for driving eccentric rotating mass (ERM) or linear resonant actuators (LRA). The board includes the DRV2625 along with the required passive components to operate the DRV2625. Simply connect power, I2C communication, and an actuator to get started with the DRV2625.

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.
