Suzhou Naxin Microelectronics Co., Ltd. (hereinafter referred to as "Naxin Micro"), a leading domestic signal chain chip and solution provider, announced the launch of the first domestic single-chip pressure sensor signal conditioning chip NSA© with automotive-grade LIN bus interface 9262. This product belongs to the NSA©926XX series of automotive pressure sensor signal conditioning chip product series, supports LIN bus physical interface communication mode, and can be widely used in automotive air conditioning and thermal management systems, intake/exhaust management systems, fuel vapor management systems and brakes Various electronic control systems such as power assist system.
As the first domestic single-chip pressure sensor signal conditioning chip with integrated LIN bus interface, NSA©9262 meets the AEC-Q100 Grade 0 standard, has a 24-bit resolution accuracy, and supports a wide operating temperature from -40°C to 150°C Range, its internal integrated over-voltage protection circuit can be directly powered by the car's 12V battery. At the same time, NSA©9262 integrates a dual-channel high-precision analog front end, which supports four-point third-order nonlinear calibration and second-order temperature calibration of pressure sensors, minimizing the need for external components, thereby further reducing the overall system cost.
The product belongs to the NSA © 926XX series of automotive pressure sensor signal conditioning chip product series. It supports LIN bus physical interface communication. It can be used in a wide range of electronic control systems, air conditioning systems and other safety management and thermal management systems, and fuel vapor management systems. As the first automotive-grade single-chip pressure sensor signal conditioning chip with integrated LIN bus interface, NSA ©9262 complies with AEC-Q100 Grade 0 standard, 24-bit precision, high-resolution accuracy, wide operating temperature range from-40°C to 150°C, The internal integrated back-pressure protection circuit can be directly powered by the car's 12v battery. At the same time, NAS©9262 integrates a high-precision analog front end, which supports four-point third-order non-linear calibration and second-order temperature calibration of the pressure sensor, thereby minimizing the need for external components, thereby further reducing the total cost of the system.
With the development of automobile-related technologies and the increasing requirements for driving experience, automobile intelligence has become an inevitable trend.
To cope with the increase in body network ECUs and the reduction of interior space, LIN bus communication networks are increasingly being used in vehicles with pressure sensors, especially in automotive air conditioning systems and thermal management. NSA9262 and NSC9262 can be equipped with a pressure sensor for the resistance bridge principle and a pressure sensor for the ceramic capacitor principle, respectively.
