Allegro MicroSystems, Inc. (“Allegro”) (Nasdaq: ALGM), a global leader in sensing and power solutions for motion control and energy-efficient systems, today introduced theA17700，用于电阻桥梁压力传感器的汽车级接口IC，具有顶部线信号调节算法。Built on decades of automotive sensor expertise, the A17700 delivers premium performance and increased system efficiency with flexible interface options – all in a small form factor.
市场领先的功能包括：
- Flexible compensation algorithms for accuracy over temperature and sensing bridge variation;
- Precise pressure information delivery in low delay analog, PWM, or SENT outputs;
- Automotive AEC-Q100 Grade 0 qualification and EMC robustness with minimized external components;
- A suite of advanced integrated system diagnostics.
The A17700 is configurable for resistive bridge pressure sensors in a wide range of critical applications in today’s efficiently designed cars; from high-pressure systems like dynamic brake systems (DBS) in turbo and hybrid electric vehicles (HEV) or gasoline direct injection (GDI) to medium and low-pressure systems such as brake boosters, HVAC applications for electrified vehicles, and automatic transmission oil management.
High accuracy output with flexible compensation
With its best-in-class integrated polynomial algorithm, theA17700interface sensor offers high accuracy over pressure and temperature through two-stage processing of a pressure signal.这种灵活的补偿在电阻膜中提供高精度，在组装期间需要高或低点表征。
Striking a balance highly desired by system designers, this device offers ways to improve system output and maintain flexibility. With robust EMC performance – up to 4kV HBM – the A17700 also enables up to 30% fewer external components for a smaller total solution footprint, smaller PCB, and more cost-efficient system design.
“A17700允许系统设计人员轻松选择最佳算法和I / O选项，最能符合其系统要求，平衡精度和线路的测试时间，从而优化系统成本，”传感器的产品经理Haeyoung Choi解释说明Allegro的接口IC。“占地面积小，柔性补偿，A17700是适用于当今电气和混合动力电动汽车的空间和效率的应用的理想解决方案。”亚博尊贵会员
Fast output response through analog or digital standard interfaces
With parallel processing paths for input and temperature, theA17700可以达到市场上最小的芯片延迟。输入到输出处理延迟为100μs, this ultra-fast interface sensing IC允许系统补偿对膜上的振动效应，没有输出分辨率损耗，进一步增加系统保真度。
“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。”
安全关键系统诊断套件
环境条件，例如电源电压电平，温度，输入桥信号和连接的变化，可能导致压力传感系统中的临时故障。A17700捕获这些更改并在输出协议中发出信号，使系统级别能够在系统级别进行故障过滤，以获取更准确的安全通知。
The A17700 is available in a small form-factor 24-pin 4 mm × 4 mm QFN package with wettable flanks - ideal for ensuring reliable soldering and visual inspection of solder joints.
