【经验】迈来芯MLX92242二线霍尔开关实现摩托车齿轮转速测量的方法
在测量齿轮转速的应用中,迈来芯有两款非常好的转速传感器mlx90217&mlx90254,利用霍尔的原理可以精确测量每个齿轮转过的齿数从而计算齿轮的转速,且不受齿轮磨损的影响。但是在一些摩托车齿轮转速的应用当中,由于之前产品的定义问题,要求需要采用2线制的传感器来计算转速,而mlx90217&mlx90254都是3线制的传感器,遇到这种场景时就不太适用。
这里就介绍一种通过迈来芯二线制霍尔开关MLX92242来实现摩托车齿轮转速测量的方法,同样不会受到齿轮磨损的影响。
在调试的时候,我们将霍尔开关mlx92242安装在固定位置,将条形磁铁置于mlx92242背面。
如下图所示:
由于摩托车齿轮大多是软磁材料,每次转动齿轮时会引起mlx92242表面的磁通量发生变化,在经过如图所示的BOP位置时我们用迈来芯的标定工具PTC04将mlx92242标定为BOP点,转动到BRP点时标定为BRP点,这样,我们在每次转动齿轮的时候,都能检测到高低电平变化。
硬件参考设计
通过检测VHsense的高低电平变化就可以计算出齿轮转过的齿数,从而精确换算出转速。

【产品】采用2线设计的霍尔开关传感器,可优化空间受限的应用
MLX92242/MLX92241/MLX92221的工作电压范围为2.7V~24V,具有极佳的ESD/EMI性能。
【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
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。
