ATS696 Crankshaft Position Sensor IC with Speed and Direction Output

The ATS696 is a combined Hall-effect sensing integrated circuit and EMC protection circuit that provides a user-friendly, PCB-less solution for crankshaft applications.

ATS696采用了一个三个霍尔元素Hall IC，响应于由黑色目标产生的差分磁信号而切换。IC包含一个复杂的补偿电路，旨在消除磁体和系统偏移的不利影响提供速度和方向信息。模拟信号的数字处理提供零速度性能，独立于气隙，并且还可以将设备性能的动态调整到需要降低振动灵敏度的汽车应用中的典型操作条件。亚博尊贵会员阈值中的自适应切换阈值和滞后减少了与许多汽车应用中使用的目标相关联的磁信号中的任何异常的负效应。亚博尊贵会员高精度与方向信息的组合在与止动发动机设计相关的反对阶段的情况下提供绝对曲轴位置。

Customer-programmable thresholds allow fine adjustment of switchpoints for compensation of mechanical tolerances.

Customer-programmable options through EEPROM allow for performance optimization to meet specific application requirements.

The ATS696 is available in a lead (Pb) free 3-pin SM package with a 100% matte-tin-plated lead-frame.
