精简耐用的可编程线性霍尔效应传感器

简介

新的HAL 24xy产品系列提供扩展的距离测量，更加耐用，为恶劣环境下的应用提供艺术级的诊断功能。
系列中的新产品延续了Micronas线性霍尔效应传感器的长期成功，全部本厂生产，并且有汽车级百万产品零缺陷记录。产品使用Micronas最新技术，新的数码架构和加强的霍尔片。16个可编程标定点实现更有弹性的补偿功能，这让产品提供更好的输出线性度。此外，可以仅用一个简单的磁铁配置就可以测量上至 180°的角度。

诸如磁场范围，敏感度，偏置（零磁场下输出电压）和温度系数等主要特性在非易失性内存中是可编程的。产品具有带旋转电流偏置补偿的温度补偿霍尔片，一个带输出驱动的直流／交流转换器，为标定数据和输出数据提供冗余和锁定功能的EEPROM内存，对EEOROM编程的一系列界面，和各引脚保护装置。
通过简单标定，产品可很好地调整输出输入信号并且补偿应用中的所有偏差（磁铁位置，温漂）。这让产品在全温度范围内精确工作。通过PC电脑和Micronas工具包就能轻易实现对各别传感器参数的计算和EEPROM编程。
产品设计适用于恶劣环境下的工业和汽车应用。HAL24xy系列有小尺寸铅 RoHs TO92UT封装，AECQ100合规。从2014年第二季度起也提供SOIC8封装。

框图 － 系统架构

HAL24xy是一块单体集成电路，提供比例于霍尔片磁通量和供电电压的输出。电压转换成数码值，在数码信号处理单元（DSP）中按照EEPROM设置来处理，转换回模拟比率电压，以推拉电容缓冲（HAL 242x）。HAL 2455有可配置的12位分辨率脉宽调制输出，频率在0.25 kHz 和 2 kH之间。
