【选型】工作电压范围为2.7~24V的电流输出型霍尔开关MLX92242适用于汽车TCU系统，有效节约成本

时间： 2023-04-19 来源：世强

技术问答

在汽车TCU系统中，有多个位置需要用到转速传感器用来测量系统内的传速比。在这个系统中，由于使用的环境比较复杂，产品要有很强的抗干扰能力。锁存型芯片只有在磁极发生变化的时候，信号才会发生变化，电流型芯片的信号取出是从回流地端取出。通过在地端的的分压电阻，直接取出电压信号。本文介绍迈来芯电流输出型霍尔开关 MLX92242的应用优势。

MLX92242产品特性如下：

1、产品工作电压范围2.7~24V，工作电流最大20mA。

2、产品是锁存型输出，触发磁场范围 ±12 mt 。

3、电流型输出方式，信号输出从回流的负端通过采样电阻取出。

MLX92242在车载TCU项目中的应用的主要优势有：

1、两线制产品，能够帮助客户节约设计成本。

2、电流输出型设计有很好的抗干扰特性。

3、锁存型磁场感应特性，对于恶劣的磁场环境有很好的抑制。

MLX92242目前支持的磁铁运动方式如下图：

用户可根据上图中的任意一种方式选择合适的结构设计来做匹配。
