Description

ATS642 是经优化的霍尔效应集成电路，可为双线式应用的真零速数字环形磁铁感测提供用户友好型解决方案。 该器件采用单脉冲模压塑料封装，其中包括钐钴磁铁、极片以及专为磁路优化的霍尔效应 IC。 该小型封装便于组装并能与各种形状及尺寸的齿轮一同使用。

该集成电路将双元件霍尔效应传感器与信号处理相结合，可响应铁氧体齿轮产生的差分磁性信号而进行开关操作。 该电路包含精密数字电路，可减少系统偏置、校准气隙独立开关点的增益并实现真零速操作。 器件通过偏置和增益调整在通电时优化信号，并使用运行模式校准保持工作期间的信号优化。 运行模式校准可保护目标不受诸如微振荡或突然气隙变化等环境影响。

为双线式应用配置稳定电流输出,该器件特别适合获取 ABS 中的速度和占空比信息（防锁死刹车系统）。 经优化的双霍尔元件之间 1.5 毫米的间距专为基于齿轮齿的细距配置。该封装为无铅封装，采用 100% 雾锡电镀引脚框。
