  • Product introduction

A3213 和 A3214 集成电路是带有锁存数字输出的超灵敏、不受磁极约束的Hall-effect switches。它们尤其适用于电池供电型、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。2.4 至 5.5 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 825 µW(对于 A3213)和 14 µW(对于 A3214)以下(在 2.75 V时)!A3213 和 A3214 除工作循环和平均工作电流以外,其他特征均相同。

with othersHall-effect switches不同的是,只要北极或南极的磁场强度足够大,就能打开输出;没有磁场的时候,输出就会停止。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。

Stabilization chopping (dynamic offset cancellation) improves stability and reduces residual offset voltages typically caused by device overmolding, temperature dependence, and thermal stress.

这些器件将霍尔发电机、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。先进的 BiCMOS 工艺用于利用低电压和低功率请求、元件匹配、极低的输入偏差错误和小型元件几何尺寸的优势。

范围 "E" 的器件的额定工作温度为 -40°C 到 85°C,而范围 "L" 的器件的额定工作温度为 -40°C 到 150°C。两种封装型号都能为大多数应用提供磁性优化的封装。‘LH’是一种微型低厚度表面安装型封装,'UA'则是用于过孔安装的三引脚 SIP。对于 A3213,还可提供微型无铅 DFN/MLP 封装'EL'。所有封装均为无铅版本(后缀,–T),引脚框采用 100% 雾锡电镀。
