DRV2605 器件设计用于通过共享的 I2C 兼容总线提供极为灵活的 ERM 和 LRA 传动器触控。该控制使得主机处理器不用再生成脉宽调制 (PWM) 驱动信号,从而节省了代价高昂的定时器中断和硬件引脚。
DRV2605 器件具有内容丰富的集成库,可提供来自 ERM 和 LRA Immersion 的 100 多种已获许可的效果,从而免除了对设计触控波形的需要。
DRV2605 器件可提供许可版本的 Immersion TouchSense 2200 软件,其中包括 2200 效果库和 2200 音频至气氛 功能。此外,主机处理器可利用实时回放模式绕过库回放引擎并通过 I2C 从主机直接播放波形。
DRV2605 器件还包含一个智能环路架构,此架构可轻松实现 LRA 自动谐振驱动以及优化反馈的 ERM 驱动。这种反馈提供了自动过驱和制动,从而生成了一个简化的输入波形图并实现了可靠的电机控制和稳定的电机性能。音频至触觉模式自动将音频输入信号转换为实际的触控效果。
DRV2605 器件 具有 一个经三重调制的输出级,从而能够提供比基于线性的输出驱动器更高的效率。DRV2605 器件采用 9 焊球 WCSP 封装,具有很少的组件数量,操作灵活,是支持触控的便携式振动和触觉 应用的理想选择。
