HAL730SF-E中文资料两路独立输出的双霍尔效应传感器数据手册TDK-Micronas规格书

描述 Description

HAL 7xy是配有S1、S2两个独立CMOS技术霍尔片的单体霍尔效应传感器，有两个开漏输出。HAL730具有计数和方向输出。计数输出根据磁场接近霍尔片S1的情况作霍尔感应开关活动。方向输出指明磁介质线性或者旋转运动的方向。配合活动的对象交替输出磁场N或S极，产品就能产生用于控制对象位置、速度和方向的信号。HAL7xy包含温度补偿和主动偏置补偿。这些特性在全温度和全电压范围内提供了优越的稳定性，以及适应机械应力的开关点。HAL 7xy产品系为工业和汽车应用设计，工作电压范围从3.8伏到24伏，环境温度范围从–40 °C 到170 °C。产品有 SMD OT89B封装。

特性 Features

·Operates from –40 °C up to 170 °C junction temperature
·Operates from 3.8 V to 24 V supply voltage
·Generation of a direction signal (HAL 730 only)
·Operates with static magnetic fields and dynamic magnetic fields up to 10 kHz
·Overvoltage protection at all pins
·Reverse-voltage protection at VDD pin
·Magnetic characteristics are robust against mechanical stress effects
·Short-circuit protected open-drain outputs by thermal shut down
·Constant switching points over a wide supply voltage and temperature range
·The decrease of magnetic flux density caused by rising temperature in the sen- sor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics
·High temperature stability for automotive or industrial applications
