HAL549UA-E数据手册TDK-Micronas中文资料规格书

描述 Description

HAL 5xy系列由各种以CMOS生产的霍尔开关组成。它们都具有主动温度偏置补偿，比较器和开漏输出晶体管。比较器通过霍尔片（霍尔电压）比较实际磁通量和设定的参考值（开关点）。输出晶体管相应开或关。
这系列的不同产品以开关行为和开关点来区分。主动偏置补偿带来在电压和温度范围变化下的稳定磁场数据。此外，磁参数对机械压力效应不敏感。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150 °C。产品有 SMD-封装 SOT89B-1和含铅的TO92UA-1和TO92UA-2封装。
