HAL2833UT-A中文资料SENT输出的霍尔效应线性传感器数据手册TDK-Micronas规格书

描述 Description

HAL283x产品是 Micronas varioHAL® (HAL 28xy)可编程线性霍尔效应传感器系列的成员。
产片带有数码SENT（单边缘蚕食传输）界面。该界面支持在恶劣环境下汽车应用的快速和稳定的数据传输。该界面的应用符合SAE J2716 SENT 标准2010-01版。
每条SENT信息含有一系列的脉冲。在一个协议里，传感器传输磁场信息，传感器状态信息，以及基于安全考量的CRC校验和。也可选择在每个协议里加一个停顿脉冲实现同步传输。
内部的数字信号处理是产品的一大优势，因为模拟偏置、温度飘移和机械应力并不降低传感器的精度。
诸如磁场范围，敏感度，偏置和温度系数等主要特性在非易失性内存中是可编程的。
HAL  283x有超小尺寸TO-92UT铅封装。
