The new MLX90818 is a packaged absolute pressure sensor that is factory-calibrated to cover the range 1.0 to 5.5 bar, making it ideal for normally aspirated, direct injection and turbocharged engine applications. The highly integrated sensor includes provision for an external NTC for temperature measurement and is housed in a tiny 4 x 5mm DFN package.
As the only component solution available without exposed corrodible metals, the device offers the best harsh media compliance, especially against the harsh halogens found in high concentrations in modern engines that are both downsized and lighter. The MLX90818 has 18V overvoltage capability and can operate from -40°C to +150°C, making it suitable for all under-the-hood applications.
Pressure accuracy is a market-leading ±0.5% to ±0.75% for extended life operation at 150°C, allowing highly accurate MAP and EGR sensors to be built, thereby reducing significantly the NOx emissions that contribute to pollution and the CO2 emissions that contribute to global warming.
“The ability to work in the harshest environments with unprecedented levels of accuracy means that this device will make a significant contribution to developing highly efficient and cleaner vehicles, thereby reducing pollution and preserving the environment,” Laurent Otte, pressure sensors product line manager, said.
