【选型】迈来芯单极性霍尔开关MLX92231替换AKM旭化成EW450/B，助力热水器步进电机零位检测应用

时间： 2020-12-29 来源：世强

技术问答

新一代燃气热水器使用步进电机代替常规燃气比例阀，进行燃气输出控制模块，步进电机能精确控制进气量达到温度的准确控制。步进电机只能检测增量信息，初始的零位检测一般采用霍尔开关的方案。热水器行业安全稳定性要求高，工作电压一般采用36V，而且点火脉冲对电子元件的ESD和EMC性能也有要求。基于性能和精度的高要求，霍尔开关目前一般采用欧美和日本厂商的产品。

针对热水器步进电机模块的需求，迈来芯推出高品质单极性霍尔开关MLX92231。MLX92231属于单极性霍尔开关，初始位置霍尔开关靠近磁铁，霍尔开关使能输出有效电平（低电平），步进电机运动使霍尔开关离开磁铁输出高电平，从而实现零位检测。MLX92231系列提供多种Bop/Brp版本选择，根据行业经验选择Bop为10mT的型号：MLX92231LSE-AAA-010，Brp为8.5mT，磁滞小零位检测更准确。

下面是MLX92231LSE-AAA-010和旭化成EW450的性能对比，可以看出迈来芯产品MLX92231供电范围更宽、磁滞更小、工作电流更低、温度ESD性能更加优越，更适合热水器中零位检测应用。

【选型】迈来芯单极性霍尔开关、双极性霍尔开关和全极性霍尔开关适用于智能门锁和笔记本电脑等多种场景，可满足不同应用需求

霍尔开关是常见的霍尔开关，它主要是利用霍尔元件做成的开关，霍尔元件其实是一种磁敏元件。霍尔开关的检测原理主要是针对带磁性的物件靠近产生的状态变化，当霍尔开关上面的元件因为磁性物体靠近就会产生霍尔效应，使开关内部的电路状态产生变化，达到控制开关通电或者断电的状态。
