Allegro介绍了传感器接口IC,为电阻桥压力传感器提供高精度和输出灵活性

二月22,2021

The A17700 delivers fast, reliable, and flexible output with top-of-the-line signal conditioning algorithms for automotive and industrial pressure sensing applications.

亚博棋牌游戏Allegro Microsystems,Inc。(“Allegro”)(纳斯达克:alGM),是运动控制和节能系统的传感和电力解决方案的全球领导者,今天介绍A17700,一个automotive-grade interface IC for resistive bridge pressure sensors featuring top-of-the-line signal conditioning algorithms.建于几十年的汽车传感器专业知识,A17700提供了优质的性能和利用灵活的接口选项提高了系统效率 - 全部采用较小的形状因素。

市场领先的功能包括:

  • 灵活补偿算法,用于精度超过温度和传感桥梁变化;
  • 低延迟模拟,PWM或发送输出中的精确压力信息输送;
  • 汽车AEC-Q100等级0级资格和EMC具有最小化外部组件的鲁棒性;
  • 一套高级集成系统诊断。

A17700可配置用于当今有效设计的汽车中各种关键应用中的电阻桥梁压力传感器;亚博尊贵会员从涡轮和混合动力电动车(HEV)的动态制动系统(DBS)等高压系统或汽油直接注射(GDI)到中低压系统,如制动助剂,用于电气化车辆的HVAC应用,以及自动变速器油亚博尊贵会员管理。

具有灵活补偿的高精度输出

凭借其最佳的集成多项式算法,A17700接口传感器通过压力信号的两级加工提供高精度和温度的高精度。This flexible compensation delivers high accuracy in resistive membranes requiring either high- or low-point characterization during assembly.

通过系统设计人员突击高度期望的余额,该设备提供了提高系统输出并保持灵活性的方法。具有强大的EMC性能 - 高达4kV HBM - A17700还可以为较小的全解决方案占地面积,较小的PCB和更具成本高效的系统设计提供高达30%的外部组件。

“The A17700 allows system designers to easily select the optimal algorithm and I/O options that best fit their system requirements, balancing accuracy and end-of-line test times, thereby optimizing the system cost,” explains Haeyoung Choi, Product Manager for Sensor Interface ICs at Allegro. “With its small footprint and flexible compensation, the A17700 is the ideal solution for applications where space and efficiency matter, like in today’s electric and hybrid electric vehicles.”

通过模拟或数字标准界面快速输出响应

具有输入和温度的并行处理路径,A17700can achieve the smallest chip delay on the market. With an input-to-output processing delay of 100μs,这款超快速接口感应ICallows systems to compensate for vibration effects on the membrane with no output resolution loss, further increasing system fidelity.

“此快速设备响应时间使得能够更快的输出采样,允许系统过滤不希望的膜振荡,”添加Choi。“这种报告振荡能力的增强能力将确认应用了适当的过滤,并为客户提供值得信赖的可靠性和性能。”

Suite of diagnostics for safety-critical systems

Environmental conditions, such as a change in supply voltage level, temperature, input bridge signal, and connection, can cause temporary faults in pressure sensing systems. The A17700 captures these changes and signals them in the output protocol, enabling fault filtering at the system level for more accurate safety notifications.

A17700采用小型24引脚4mm×4mm QFN套件,具有可湿性侧面 - 非常适合确保焊点的可靠焊接和目视检查。
