It is easy to use with either the factory calibration, Melexis’ firmware, or custom firmware, and is compatible with other integrated functions like the temperature sensor and battery monitoring.
This Melexis-designed MEMS pressure sensor is based on very reliable technology, with a thick membrane and a sealed cavity. Melexis’ smart packaging approach makes it easy to integrate into a system, and it is inexpensive. The absolute pressure measurement uses a soft coating rather than complex packaging with manifolds.
This report presents a detailed analysis of sensor structure and cost, as well as a characteristics comparison between Infineon’s SP37, Freescale’s FXTH87, and Melexis’ MLX91802, highlighting the different technical choices made by each company.
