【经验】解析MELEXIS电流性霍尔开关MLX92242用于位置检测的开发注意事项
伴随着目前电子行业的飞速发展,对于原来通过干簧管或机械结构做相关到位检测的机制,现在不少人想通过霍尔的方案进行设计。而对于汽车油盖开盖检测等一些距离主控比较远的位置,很多人倾向于用MELEXIS的电流性霍尔开关MLX92242进行设计。而针对这种位置检测在开发时的一些注意事项,在这里给大家做些分享,希望对大家能有所帮助。
首先,MLX92242的参考设计如下,这里我们需要注意的是MLX92242输出的是电流信号,所以,在电路采集端需要增加一个下拉电阻,这样才能将相关电流信号转换为相应的电压信号,便于采集端采集。同时,需要注意的另一个点是下来电阻要尽量靠近采集端端口而不是靠近MLX92242,这样可以避免线缆长度对于MLX92242输出信号的影响。
另外,MLX92242具备多个型号其主要分为锁存器和开关型。这种在我们做相关设计时需要结合我们对于动作情况的需求进行选择,若我们只是实现磁铁某一个极性靠近和远离而输出相关开关量,从而确定当前的移动情况,那么这种情况我们要考虑用开关型。而若我们需要实现磁铁一个极性靠近时动作,而另一个极性靠近时再做相关动作释放,这个需要考虑用其锁存器版本。当然,本身MLX92242是可编程的,我们也可以通过配置对其动作情况做调整也是可以的。
最后,对于MLX92242而言,我们需要注意它具备IMC版本和通用版本。对于通用版本而言其只具备检测垂直于芯片表面的磁场,而IMC的是可以检测平行于芯片表面的磁场。这个我们在做设计时也要注意一下,结合我们实际结构设计,确定当前磁场相对于芯片的分布轨迹,从而确认合适的芯片版本,提高产品设计的成功率。
