  • Product introduction

Linear outputHall-effect sensors的新应用(如位移和角位等)要求更高的精确度和更小的封装尺寸。Allegro A1318 和 A1319 线性霍尔效应传感器 IC 专为满足上述要求而设计。表面贴装封装和通孔插入式封装均具有上述热稳定器件。

每种器件的精确度都可以通过下线优化得到提高。每种器件都配有非易失性存储器,可针对给定应用或电路优化器件灵敏度和静态电压输出(QVO:在没有磁场的情况下的输出)。通过在 Allegro 下线测试中对温度系数进行编程,以实现高灵敏度和 QVO,A1318 和 A1319 还可在整个工作温度范围内实现最佳性能。

这些成比例霍尔效应传感器 IC 提供与所施加的磁场成比例的电压输出。静态电压输出可调整为电源电压的 50% 左右。

凭借其各项特色功能,这些线性器件非常适合要求高准确度的汽车和工业应用,并能在 –40°C 到 150°C 的温度范围内正常工作。

各 BiCMOS 单片电路均整合可降低霍尔元件固有灵敏度漂移的霍尔元件温度补充电路、小信号高增益放大器、箝位低阻抗输出级和专有动态偏移消除技术。

A1318 和 A1319sensorIC 采用两种封装形式。LH 是表面贴装用 SOT-23W 微型低剖面封装。UA 是通孔插入用三引脚超小型单列直插式封装 (SIP)。两种封装均为无铅 (Pb) 封装,采用 100% 雾锡电镀引脚框。

  • 3.3 V 电源供电
  • Allegro 编程的 QVO 温度系数™有助于提高精确度
  • 小型封装选择
  • 高带宽、低噪音模拟输出

  • 温度稳定的静态电压输出及灵敏度
  • 温度周期性变化后精确的可恢复性
  • 输出电压钳位具有短路诊断功能
  • Undervoltage lockout (UVLO)
  • 较宽的环境温度范围:–40°C 到 150°C
  • 抗机械应力
  • 更高的 EMC 性能,满足严格的汽车应用要求
