Melexis汽车级线性霍尔效应传感器MLX90290，PIN-TO-PIN替换A1301、A1302,功耗和温漂更小

时间： 2019-03-05 来源：Melexis

技术问答

MELEXIS作为全球先进的驱动和传感器研发和生产领先者，以其先进的技术和创先能力，赢得了广大客户的认可。霍尔传感器是一种基于霍尔效应的传感器，线性霍尔传感器一般由霍尔器件、差分放大电路和射极跟随器等组成的，其输入是磁感应强度，输出是和输入量成正比电压。线性霍尔传感器拥有很宽的磁场工作范围，关键性指标是在其规定的温度范围灵敏度和线性度，几乎不受环境因素影响，如潮湿、油污、灰尘、环境照明灯等；

MLX90290是Melexis第二代线性霍尔效应传感器，输出的偏置电压（静态）在0磁场下等于50%VDD，封装有两种，分别为TSOT-3L及TO-92-3L，可满足汽车级应用的苛刻要求，可PIN-TO-PIN替换Allegro线性霍尔传感器A1301、A1302，具体对比如下。

封装对比

通过上图封装对比，MLX90290可PIN-TO-PIN替换A1301和A13022；

参数对比如下

通过上面参数对比，可以看出MLX90290替换A1301和A1302，不仅仅功耗和温漂更好，而且还具有以下优势：

Ø 通过工作温度对比，MLX90290范围更宽，能够使产品工作在更加恶劣的环境；

Ø 通过灵敏度对比， MLX90290磁铁选择更多；

Ø 通过线性误差对比，MLX90290明显优于A1301和A1302；

汽车级线性霍尔效应传感器MLX90290的优势特性：

Ø 满足汽车级应用的苛刻要求。

Ø 符合RoHS标准

Ø 工厂可编程、支持客户预编程；

由上述对比可知，迈来芯线性霍尔传感器MLX90290 PIN-TO-PIN替换A1301和A1302，不仅提高工作温度范围，而且测量精度、抗干扰能力都大大的提高。如果您感兴趣记得收藏和点赞哦，感谢！有问题请留言或电话联系世强400-887-3266
