Facilitate Emission Reduction with NOVOSENSE Automotive Absolute Pressure Sensor NSPASx Series
SHANGHAI, May 17, 2022 /PRNewswire-AsiaNet/ --

To realize full combustion and reduce emissions, the engine of 
automobile/motorcycle usually requires a temperature pressure sensor on the 
intake manifold (TMAP) to control the air-fuel ratio quickly and accurately, 
which can build a balance between power performance, fuel economy and 
emissions. The automotive absolute pressure sensor with response time in 
sub-millisecond is one of the key components in combustion engine system to 
realize closed loop control. There is also the same requirement in the 
gas-driven models to reduce emission with the pressure sensor near the gas 
injector.

Semiconductor Supplier NOVOSENSE Microelectronics recently launched its NSPASx 
series --- an automotive-qualified integrated absolute pressure sensor which 
integrates the automotive-qualified absolute pressure MEMS die(NSP163x) and 
signal conditioning IC(ASIC). The device adopts ASIC to calibrate and 
compensate the output of MEMS die, which can convert pressure signals from 
10kPa to 400kPa into Vout with a customized output range from 0 to 5V. The 
internal MEMS die is based on the piezoresistive effect of high-sensitivity 
monocrystalline silicon and is designed with advanced silicon-silicon bonding 
CSOI MEMS micromachining technology which has been certified by IAFTF16949. The 
whole wafer has 100% passed AOI and CP test and also the AEC-Q103 
qualification, total accuracy is less than +/-1%FS during its life cycle.

The NSPASx series and MEMS wafer(NSP163x) are mainly used in intake manifold 
pressure detection of vehicle/motorcycle, purging line pressure detection of 
vehicle, vacuum boosting system (VBS) pressure detection of HEV/EV, thermal 
runaway pressure detection of battery pack, as well as the car seat airbag 
pressure detection.

Key features:

High accuracy and low power consumption:
High linearity and good stability without secondary calibration
100% temperature compensation
Output accuracy better than +/-1%F.S. at 0 degrees Celsius ~ 85 degrees 
Celsius, better than +/-1.5%F.S. at -40 degrees Celsius ~130 degrees Celsius
Operating current less than 3mA
Multiple output modes with good portability for various applications:
Ratio-metric analog output
Absolute analog output
Automobile-level standard with high reliability and stability:
Over-voltage and reverse-voltage protection between -24V to 28V
Directly supplied by high voltage up to 18V
AEC-Q100 qualified
Quick response to control the ratio of air-fuel speedily:
Better than 0.8ms response time
Customization for different applications with high flexibility:
Support the customization of pressure range from 10kPaA to 400kPaA
MEMS wafer(NSP163x) can also be customized

NOVOSENSE Microelectronics has self-developed MEMS/ASIC, packaging technology 
and automatic calibration technology at multi-pressure and multi-temperature 
points, which can support MEMS wafer and integrated device customization to 
meet the requirements in multi-applications.
