  • Product introduction

A3211 和 A3212 集成电路是带有锁存数字输出的超灵敏、不受磁极约束的霍尔效应开关。这些器件尤其适用于电池供电、手持型设备的操作,例如移动和无绳电话、传呼机以及掌上型电脑。2.5 至 3.5 V工作电压范围和独特的时钟方法,能将平均操作功率要求降低到 15 µW 以下(2.75 V 电源电压时) 。

与其他霍尔效应开关不同的是,只要北极or南极磁场强度足够大,就能打开 A3212 中的输出,没有磁场的时候,输出就会停止。A3211 提供反向输出。不受磁极影响和最低的功率要求,允许这些器件轻松取换簧片开关,具有更高的可靠性并便于制造,从而降低对信号条件的要求。

稳定斩波(动态偏移取消)提升了稳定性,可降低通常由器件超模压、温度依存性及热应力引起的剩余偏移电压。

该器件将霍尔发电机、小型信号放大器、稳定斩波特性、锁存和 MOSFET 输出集中在单硅片上。运用先进的 BiCMOS 工艺,实现低电压和低功率要求、元件匹配、极低的输入偏差错误和小型元件几何尺寸。

四种封装类型能为大多数应用提供磁性优化的解决方案。微型低厚度表面安装封装类型 EH 和 EL(标高为 0.75 和 0.50 mm)不含铅,LH 是三引脚低厚度 SMD,而 UA 则是用于过孔安装的三引脚 SIP。该封装为无铅封装(后缀 –T),引脚框采用 100% 雾锡电镀。
