DRV5015A3QDBZT传感器变送器的磁性传感器-开关（固态）规格书PDF中文资料

DRV5015A3QDBZT属于传感器变送器的磁性传感器-开关（固态）。由美国德州仪器公司制造生产的DRV5015A3QDBZT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 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.
