3 说明

DRV2605L-Q1 器件是一款一款汽车触觉驱动器，其包含触觉效果库和闭环致动器控制系统，可为 ERM 和 LRA 提供高质量的触觉反馈。此方案有助于提升致动器在加速度稳定性、启动时间和制动时间方面的性能，通过共用的 I2C 兼容总线或 PWM 输入信号即可触发该方案。

DRV2605L-Q1 器件提供了 Immersion 公司的许可版 TouchSense 2200 软件，其中包含 100 多种许可版效果（6 个 ERM 库和 1 个 LRA 库）和 audio-to-vibe 功能，因此无需设计触觉波形。 特性。

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。

DRV2605L-Q1 器件内部采用智能环路架构，可轻松实现自动谐振 LRA 驱动，以及优化反馈的 ERM 驱动，从而提供自动过驱动和制动。这种智能环路架构可构建简化的输入波形接口，并且能够提供可靠的电机控制和稳定的电机性能。 DRV2605L-Q1 还可以利用内部生成的 PWM 信号实现开环驱动。 此外，“audio-to-vibe”模式可自动将音频输入信号转换为实际的触控效果。

有关 Immersion 软件的重要说明，请参阅 法律声明 部分。
