触觉电机驱动器

Produce crisp, powerful vibration effects for any touch interface application

Haptics vibration effects bring another touch to user interfaces in place of conventional buttons. Our haptics motor drivers use closed-loop, auto-resonance tracking algorithms to maximize performance and minimize power consumption when driving linear resonant actuators (LRAs) and eccentric rotating masses (ERMs). Preprogrammed waveform libraries and auto-calibration features make it simple to add haptics effects to any user interface.

Evaluation board

具有蓝牙和电容式触控功能的 DRV2625 评估板

DRV2625 触觉驱动器支持各种线性共振传动器 (LRA) 和偏心旋转质量 (ERM)。DRV2625 提供多种特性来消除触觉电机控制的设计复杂性，这些特性包括较小的解决方案尺寸、改进的输出驱动器效率、闭环电机控制、快速启动以实现低延迟反馈以及自动共振跟踪。DRV2625 还大幅降低了待机电流，进而减少空闲期间的能耗。

DRV2625EVM-CT 评估模块 (EVM) 是对 DRV2625 的完整演示与评估参考设计。此套件中包括 DRV2625 触觉驱动器、LRA、ERM、示例波形、电容式触控输入和 USB 控制。

触觉加速计测量工具

DRV-ACC16-EVM 评估模块 (EVM) 可让您轻松测量触觉反馈、加速度和振动强度并确定其特性。此 EVM 使用加速计 IC 采集加速度数据，并将 X、Y 和 Z 轴数据作为一个模拟信号进行输出，随后示波器可对该信号进行测量。根据加速度数据，您可测量振动强度、启动时间、制动时间和波形形状，以比较波形、传动器和机械设计。此 EVM 使用灵活的 PCB 进行设计，可更大限度地降低加速计对机械系统的影响。
