简介

ZSSC4169 是 IDT ZSSC416x 系列 CMOS 集成电路的产品,用于对差分桥传感器信号进行高精度放大和传感器特定校正。 ZSSC4169 的最大前置放大范围为 150 至 200,几乎适用于所有电阻电桥以及电压源传感器类型。 失调、灵敏度、温度漂移和非线性的数字补偿由一个 16 位 RISC 微控制器完成。 校准系数和配置数据存储在集成的非易失性存储器(NVM)中,这在汽车应用中非常可靠。 测量值可以通过数字 SENT 读取。 SENT 接口仅使用一个输出引脚即可通过其快速通道传输传感器数据,并通过其串行数据消息(“慢速”)通道传输补充数据。 通过 I²C 接口或通过单线接口(OWI)通过数据输出引脚(DOUT)支持下线校准。 ZSSC4169 和校准设备可进行数字通信,因此噪声灵敏度大大降低。 数字校准有助于保持较低的装配成本,因为不需要外部设备或修整。 ZSSC4169 通过过压和反极性保护电路、出色的电磁兼容性和多种诊断功能针对汽车环境进行了优化。

ZSSC416x/7x Sensor Signal Conditioners Automotive Overview

Modern vehicles are filled with complex sensor systems to achieve optimal performance and lower emissions. IDT's ZSSC416x and ZSSC417x family of sensor signal conditioner ICs are ideal for use in the engine and exhaust system. Sensing differential pressure at the mass airflow intake using a single IC attached to two sensors lowers power consumption and improves accuracy compared to traditional sensing systems. Manifold pressure and temperature sensing also benefits from the use of a dual input IC, with higher accuracy measurements resulting in a more optimal fuel mix.

The IDT ZSSC416x and ZSSC417x family of sensor signal conditioners provide a platform for measurement systems with improved accuracy, reliability, and performance with lower power consumption. The family of devices provides highly accurate amplification with integrated compensation, correction, and calibration, while also sharing a common four-millimeter by four-millimeter QFN package and tool set to reduce development and assembly costs.

TRANSCRIPT

Modern vehicles are filled with complex sensor systems to achieve optimal performance and lower emissions. IDT's ZSSC416x and ZSSC417x family of sensor signal conditioner ICs are ideal for use in the engine and exhaust system. Sensing differential pressure at the mass airflow intake using a single IC attached to two sensors lowers power consumption and improves accuracy compared to traditional sensing systems. Manifold pressure and temperature sensing also benefits from the use of a dual input IC, with higher accuracy measurements resulting in a more optimal fuel mix.

High temperature sensing across the turbo-charger benefits from a simpler design and lower cost with both thermocouples connecting to the same IC. At the diesel particulate filter, IDT products enable more accurate measurements of filter saturation, resulting in less fuel waste for filter purging. Selective catalytic reduction adds urea to the exhaust to reduce harmful emissions. Improved measurement accuracy leads to better control of urea dosing, reducing urea overuse and refilling costs for the vehicle owner. By more accurately measuring temperature and pressure in the fuel line, the control unit can provide the best fuel/air mix, lowering emissions and improving engine performance.

Compared to traditional anemometers, the sensors used with IDT sensor signal conditioner products are more durable in the harsh environment of exhaust mass airflow measurements, leading to a more reliable, lower power solution. The IDT ZSSC416x and ZSSC417x family of sensor signal conditioners provide a platform for measurement systems with improved accuracy, reliability, and performance with lower power consumption. The family of devices provides highly accurate amplification with integrated compensation, correction, and calibration, while also sharing a common four-millimeter by four-millimeter QFN package and tool set to reduce development and assembly costs.
