ATS665.pdf【产品说明】Allegro MicroSystems公司的ATS665齿轮速度传感器集成了一块霍尔IC和磁体钐钴磁体，并封装在一个SG外壳中，适用于工业机械、工作速度传感、传输和交流发电机/发电机。
该模块集成的霍尔元件可消除与传统单元件督办传感器相关的后偏置磁场的变化。
SG封装还消除了封装和成形之后的空气气泡。磁体与IC封装的结合可改善散热，使得该器件工作在-40℃至160℃的温度范围。
该模块工作电压3.3V至24V，工作电流14mA。ATS665通电并经过一个校准周期后，传感器就可以提供转动齿轮的数字信息。高分解度、峰值检测的DAC用于设定切换阈值。

True Zero Speed,
High Accuracy, Gear Tooth Sensor
High Accuracy, Gear Tooth Sensor
The ATS665 true zero-speed gear tooth sensor is an optimized
Hall IC/magnet configuration packaged in a molded module that
provides a user-friendly solution for digital gear tooth sensing
applications. The sensor module consists of an over-molded
package, which holds together a samarium cobalt magnet, a pole
piece and a true zero-speed Hall IC that has been optimized to the
magnetic circuit. This small package can be easily assembled and
used in conjunction with gears of various shapes and sizes.

Maximum Allowable Power Dissipation Calculation for ATS665:
Assume:
Ta = Tamax = 165 °C
Tj(max) = 165°C
4 Icc = 12.0 mA
