抬头显示 (HUD) 和仪表盘

利用 Allegro 抬头显示 (HUD) 解决方案提高驾驶安全性。 HUD 是高级驾驶辅助系统 (ADAS) 中的仪表组件，可为驾驶员提供速度、转速、温度、导航和环境警报等信息。

HUD 是否优秀取决于其图像质量，而后视镜控制对于保持 HUD 图像的质量至关重要。 Allegro 的微步式步进电机驱动器采用先进的 QuietStep^TM 技术，通过减少扭矩纹波和电流失真来更大限度减少振动并进行流畅的运动控制，有助于提供稳定、高质量的图像。 QuietStep 在 PWM 周期内即时调整快速衰减量，在各种工作条件下将电流纹波保持在低水平。该自适应功能可以提高系统的性能，从而降低可闻电机噪声、降低振动并提高步进精度。

我们还提供各种用于背光照明的高度集成的 LED 驱动器，可满足您对输入电压范围、每串 LED 数、灯串数和 LED 电流的要求。我们的 LED 驱动器在可靠性和稳健性方面处于行业先进水平，具备 AEC-Q100 0 级资质，可在高达 150°C 的温度下运行，具有引脚间短路、外部组件开路/短路防范功能以及内置故障诊断功能。
