MLX90808 General Description

The MLX90808 is a fully integrated absolute pressure sensor realized with standard CMOS technology in combination with MEMS bulk micromachining. This monolithic solution is fully automotive qualified. Piezoresistors in a wheatstone bridge configuration are placed on the edges of a silicon membrane and transform the stress induced by the pressure on the membrane into an electrical signal. An analog chain interacting with a digital core performs the conditioning of the piezoresistors output voltage. By writing calibration settings in the chip memory a uniform transfer function is obtained over the working pressure and temperature range.

Even in harsh environments

The Melexis integrated pressure sensors cover many different pressure ranges from a pressure span of 100mbar to several bars. Their use is straightforward when the media to be measured is not too harsh (examples: barometers, dry air, automotive media like in engine intake manifolds, brake boosters and fuel vapor). For harsher media applications the Melexis chips are used in some special configurations (examples: oil, liquids, automotive or engine exhaust gases).

Best Performing Miniaturized Automotive Pressure Sensor

The Melexis integrated pressure sensors are proven top performers in demanding automotive applications. The sensors meet and exceed typical automotive industry quality standards. In some instances the product is qualified far beyond typical automotive quality standards. Outstanding accuracies after calibration have been achieved in applications requiring a miniaturized, compact pressure sensor solution. Melexis integrated pressure sensors are fully programmable through the connector with built in protection against all typical overvoltage automotive conditions. The integrated sensors include circuitry to all meet automotive diagnostic requirements including broken membrane detection, broken tracks detection, and short and open circuit conditions.
