  • Product introduction

A1341 器件是一款适用于汽车和非汽车应用并带可配置脉冲宽度调制 (PWM) 或单边半字节传输 (SENT) 输出的高精度可编程霍尔效应线性传感器集成电路 (IC)。A1341 的信号通道可通过外部编程实现灵活性,而外部编程可确保从输入磁性信号产生准确和定制化的输出电压。A1341 提供 12 位的输出分辨率并支持最大 3 kHz 的带宽。

BiCMOS monolithic integrated circuits contain:霍尔传感器元件、用于降低霍尔元件固有的灵敏度和偏移漂移的高精度温度补偿电路、小型信号高增益放大器、专有动态偏移取消电路、以及高级输出线性化电路。

通过板载 EEPROM 和先进的信号处理功能,A1341 可为增益和偏移、带宽、输出钳位及输出极性等特性提供无与伦比的客户可编程选择。多种输入磁性范围和信号偏移选择可在工厂进行预设。此外,该器件还支持单独的高温和低温以及一阶和二阶温度补偿。

A1341 的一个关键特征是能够在非线性输入磁场中产生高线性器件输出。为实现这点,该器件将输出分成 32 个相等的区段并为每个区段应用独特的线性化系数。线性化系数存储在 EEPROM 的查找表中。

A1341 采用无铅 (Pb) 4 引脚单列直插式封装(KT 后缀),引脚框采用 100% 雾锡电镀。

  • Advanced 32-band output linearization provides extremely high output accuracy and linearity even in the presence of a nonlinear input magnetic field
  • 可选数字化 SENT(单边半字节传输)或 PWM (脉冲宽度调制)输出
  • SENT 输出为 SAEJ2716 JAN2010,可兼容 Allegro 的专有增强型可编程功能
  • 客户可调整灵敏度偏移、带宽、输出极性、输出钳位、一阶和二阶温度补偿
  • All parameters can be programmed simultaneously for accurate and efficient system optimization
  • The magnetic input range (coarse sensitivity) and signal offset have been factory adjusted
  • Sensitivity temperature coefficient and magnetic offset drift can be preset in Allegro for maximum device accuracy without customer temperature testing
  • Proprietary four-phase chopper stabilization and differential circuit design techniques are used to obtain temperature-stable, mechanically stress-resistant, and very low-noise device outputs
  • 提供开路、过压和欠压诊断
  • Wide ambient temperature range: –40°C to 150°C
  • 下以 4.5 至 5.5V 的电源电压
