CST145A

    CST145A is a unipolar Hall effect switch sensor used in low contact switch applications. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier for amplifying Hall voltage, a Schmitt trigger for providing switch lag for noise suppression, and an open drain output. Bandgap regulators allow for a wide range of operating voltages.
    The rated operating temperature range of CST145A is -40 ° C to 150 ° C, and the voltage range is 2.7V to 24V.

CST145A Description/概述:
    The CST145A is a unipolar hall effect switch sensor,which is for contact less switching applications. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis for noise rejection, and an open-drain output. The bandgap regulator allows a wide operating voltage range.
    CST145A is rated for operating temperature range from -40°C to 150°C and voltage range from 2.7V to 24V.
    CST145A是一种单极霍尔效应开关传感器,用于少接触开关应用。该设备包括一个用于磁传感的片上霍尔电压发生器,一个放大霍尔电压的放大器,一个用于为噪声抑制提供开关滞后的施密特触发器,以及一个开漏极输出。带隙调节器允许一个广泛的工作电压范围。
    CST145A的额定工作温度范围为-40°C到150°C,电压范围为2.7V到24V。
