DRV5023FAQDBZR传感器变送器的磁性传感器-开关（固态）规格书PDF中文资料

DRV5023FAQDBZR属于传感器变送器的磁性传感器-开关（固态）。由德州仪器制造生产的DRV5023FAQDBZR磁性传感器 - 开关（固态）该系列产品使用固态技术来检测是否存在超过某个特定幅度和/或标示的磁场，并提供指示是否存在此类磁场的双态输出。它们与磁簧开关以及线性或罗盘型固态器件不同，前者通过使用移动机械部件来提供类似的功能，后者提供指示所施加磁场的强度和/或方向的可变输出。

3 Description

The DRV5023 device is a chopper-stabilized Hall

Effect Sensor that offers a magnetic sensing solution

with superior sensitivity stability over temperature and

integrated protection features.

When the applied magnetic flux density exceeds the

BOP threshold, the DRV5023 open-drain output goes

low. The output stays low until the field decreases to

less than BRP, and then the output goes to high

impedance. The output current sink capability is 30

mA. A wide operating voltage range from 2.5 to 38 V

with reverse polarity protection up to –22 V makes

the device suitable for a wide range of industrial

applications.

Internal protection functions are provided for reverse

supply conditions, load dump, and output short circuit

or over current.
