DRV2605LTDGSRQ1

DRV2605L-Q1器件是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。 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。

The DRV2605L-Q1 device is a low-voltage haptic driver that relies on the back-EMF produced by an actuator to provide a closed-loop system that offers extremely flexible control of LRA and ERM actuators over a shared I²C compatible bus or PWM input signal. This schema helps improve actuator performance in terms of acceleration consistency, start time, and brake time. The improved smart-loop architecture inside the DRV2605L-Q1 device provides effortless auto-resonant drive for LRA, as well as feedback-optimized ERM drive allowing for automatic overdrive and braking. These features create a simplified input waveform paradigm as well as reliable motor control and consistent motor performance. The DRV2605L-Q1 device also features an automatic transition to open-loop operation in the event that an LRA actuator is not generating a valid back-EMF voltage and automatic synchronization with the LRA when the LRA is generating a valid back-EMF voltage. The DRV2605L-Q1 device also allows for open-loop driving by using internally-generated PWM. Additionally, the audio-to-vibe mode automatically converts an audio input signal to meaningful haptic effects. The DRV2605L-Q1 device offers a licensed version of TouchSense 2200 software which eliminates the requirement to design haptic waveforms because the software includes over 100 licensed effects (6 ERM libraries and 1 LRA library) and audio-to-vibe features. The waveforms can be instantly played back through an I²C or can be triggered through a hardware trigger pin. Additionally, the real-time playback mode allows the host processor to bypass the library playback engine and play waveforms directly from the host through the I²C. The DRV2605L-Q1 device features a trinary-modulated output stage that provides more efficiency than linear-based output drivers.
