The CST4002 is Unipolar Hall effect sensor IC is fabricated from mixed signal CMOS technology. It is comprised of one Hall plate and a CMOS output drive,mainly designed for battery-operation. The total power consumption in normal operation is typically 5.6μW with a 2.8V power source. South/North poles of sufficient strength will turn the output on. The output will be turned off under no magnetic field.

    The CST4002 is available in SIP-3L, SOT23-3L,SOT553, DFN1216-4L-EP Package. Operating temperature range of the CST4002 is from -40°C to 85°C.

    CST4002是单极霍尔效应传感器IC由混合信号CMOS技术制造。是的包括一个霍尔板和CMOS输出驱动器，主要设计用于电池操作。总功率正常运行时的功耗通常为5.6μW2.8V电源。足够的南极/北极强度将打开输出。输出将为在没有磁场的情况下关闭。

    CST4002可在SIP-3L、SOT23-3L、SOT33-3L和SOT23-3R中获得，SOT553，DFN1216-4L-EP封装。操作CST4002的温度范围从-40°C到85°C。
