Texas Instruments DRV2624 Advanced ERM/LRA Haptic Driver
Texas Instruments DRV2624 Advanced ERM/LRA Haptic Driver relies on a proprietary closed-loop architecture to deliver sharp, strong, and consistent haptic effects while optimizing power consumption. The device includes internal memory, a loopable waveform sequencer, automatic overdrive, and braking. These additions simplify the process of generating crisp and optimum haptic effects, reducing the burden imposed on the processing unit. The DRV2624 features an automatic go-to-standby state and a battery preservation function. These features help reduce power consumption without user intervention. The NRST pin allows for a full shutdown state for additional power savings.Features
