DRV5032FD传感器变送器的磁性传感器-开关（固态）规格书PDF中文资料

DRV5032FD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DRV5032FD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 DRV5032 device is an ultra-low-power digitalswitch

Hall effect sensor, designed for the most

compact and battery-sensitive systems. The device

is offered in multiple magnetic thresholds, sampling

rates, output drivers, and packages to accommodate

various applications.

When the applied magnetic flux density exceeds the

BOP threshold, the device outputs a low voltage. The

output stays low until the flux density decreases to

less than BRP, and then the output either drives a

high voltage or becomes high impedance, depending

on the device version. By incorporating an internal

oscillator, the device samples the magnetic field and

updates the output at a rate of 80Hz, 20Hz or 5Hz

for the lowest current consumption. Omnipolar and

unipolar magnetic responses are available.

The device operates from a VCC range of 1.65V to

5.5V, and is packaged in a standard SOT-23, TO-92

and small X2SON.
