A1220、A1221、A1222 和 A1223:斩波稳定、精确霍尔效应锁存器

Description

Allegro MicroSystems 推荐为所有新型汽车 3 线霍尔效应锁存器 IC 设计使用  APS12200/10/30 。 

A1220、A1221、A1222, 和 A1223 霍尔效应传感器 IC 是极端温度稳定和抗应力器件,特别适合扩展温度范围的工作条件(最高可达 150°C)。动态偏移消除技术保证了在高温下的良好性能,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。每个器件在单硅片上装有以下元件:稳压器、霍尔电压发生器、小型信号放大器、斩波稳定装置、施密特触发器,以及带短路保护的开漏极输出(最大灌电流 25 mA)。强度足够大的南磁极打开输出。关闭输出需要强度足够大的磁北极。

电路板稳压器允许在 3 至 24 V的电源电压范围内工作。在 3  V 电压工作的优点是,器件可用于 3 V 的应用或可添加额外的外部电阻与电源引脚串联,实现更大的高压瞬时保护。

两种封装类型都能为大多数应用提供磁性优化的封装。LH 封装是修改的 3 管脚 SOT23W 表面安装型封装,而 UA 型是供通孔安装使用的三管脚超小型 SIP。两种封装均为无铅 (Pb) 封装,引脚框均采用 100% 雾锡电镀。
