磁性速度传感器

Allegro 提供更全面的磁性速度传感器 IC 产品组合,涵盖各种速度以及带方向的速度、两线和三线接口、磁性编码器(环形磁体)和齿轮齿感应、霍尔和 GMR 技术,以及符合 ASIL 的选项,这些选项适用于变速箱、轮速、发动机、电机和更多编码器和齿轮齿感应应用。 

创新型 Allegro 霍尔效应和 GMR 技术可提供市场上更稳健且更可靠的齿轮齿和环形磁体速度感应。

得益于数十年的应用和算法经验以及与 OEM 的密切合作,Allegro 能够根据具体应用来开发速度传感器 IC,并针对您的目标应用进行优化 — 以此提高安全性、可靠性和性能。

  • 对系统的变化(即目标跳动、振动、热梯度)进行动态补偿,可以降低设计复杂度和成本并提高可靠性。
  • 用于 EMC 保护的集成封装以及可选配的磁偏置,可简化设计和组装,同时提高性能。
  • 分立元件集成,可消除对外部 PCB 和元件的需求,从而显著降低总系统成本(第三代 GTS 封装)。
