基于MAX1452的发动机进气压力传感器的设计

摘要

According to the current modem automotive electronics technology ECU(electronic control unit, driving computer) system requirements designed an intake pressure sensor, used for electronic control engine, based on the Maxim company highly integrated sensor chip MAX1452 conditioning, realized the temperature compensation ,and other functions under the high precision acquisition implements the volume and power consumption is small, the characteristics of the sensor in the actual application shows that realizes the miniaturization, high and low temperature, strong vibration, high thermal shock and mechanical shock and chemical pollution and so on used in bad environment.%根据当前现代汽车电子技术ECU(电子控制单元——行车电脑)系统的要求设计了一种进气压力传感器,用于发动机电子控制,基于Maxim公司高度集成的传感器调理芯片MAX1452,实现了温度补偿等功能,在高精度采集下实现了其体积和功耗相当微小的特点,该传感器的实际应用表明,实现了小型化,高低温、强振动、高温冲击和机械冲击以及化学污染等恶劣环境中使用.
