DRV5015A1QDBZR傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）規(guī)格書PDF中文資料

DRV5015A1QDBZR屬于傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）。由美國(guó)德州儀器公司制造生產(chǎn)的DRV5015A1QDBZR磁性傳感器 - 開關(guān)（固態(tài)）該系列產(chǎn)品使用固態(tài)技術(shù)來檢測(cè)是否存在超過某個(gè)特定幅度和/或標(biāo)示的磁場(chǎng)，并提供指示是否存在此類磁場(chǎng)的雙態(tài)輸出。它們與磁簧開關(guān)以及線性或羅盤型固態(tài)器件不同，前者通過使用移動(dòng)機(jī)械部件來提供類似的功能，后者提供指示所施加磁場(chǎng)的強(qiáng)度和/或方向的可變輸出。

3 Description

The DRV5015 is a low-voltage digital-latch Hall effect

sensor designed for high-speed and high-temperature

motor applications. Operating from a 2.5-V to 5.5-V

power supply, the device senses magnetic flux

density and presents a digital output based on

predefined magnetic thresholds.

Alternating north and south magnetic poles are

required to toggle the output and integrated

hysteresis provides robust switching.

The device is offered in two magnetic threshold

options and an inverted output option. The high

magnetic sensitivity provides flexibility in low-cost

magnet selection and component placement.

The device performs consistently across a wide

ambient temperature range of –40°C to +125°C.
