MLX90817LXE-DCG-000-SP

Pressure Sensors Transducers Overview

The MLX90817LXE-DCG-000-SP is a packaged, factory-calibrated absolute pressure sensor IC designed for harsh media applications. It delivers a ratiometric analog voltage output ranging from 400 mV to 4.65 V across an absolute pressure range of 0.2 to 1 bar. The device operates on a supply voltage between 4.5 V and 5.5 V with a typical current consumption of 8.5 mA. It features an accuracy of 1.25% and functions within a temperature range of -40°C to +150°C. Housed in a 14-BFDFN package with exposed pads, it integrates signal conditioning and temperature compensation.

Pressure Sensors Transducers Feature Summary

• Factory calibrated integrated absolute pressure sensor delivering a ratiometric analog signal
• Optimized architecture with high-density CMOS technology for excellent harsh media compatibility
• Automotive-grade design including diagnostic capabilities such as clamp level, open circuit tracking, and internal fault detection

Pressure Sensors Transducers Applications

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix DCG-000-SP against the official Melexis datasheet to confirm the exact pressure range and calibration curve. Ensure the PCB layout accommodates the 14-BFDFN exposed pad thermal requirements. Confirm that the application environment does not exceed the specified maximum operating temperature of 150°C. Check export documentation requirements if sourcing from regions with trade restrictions.

Pressure Sensors Transducers Selection Notes

Select this component when harsh media compatibility is critical, as standard sensors may degrade when exposed to corrosive gases. The ratiometric analog output simplifies interface design compared to digital alternatives. Consider the 1.25% accuracy specification against system tolerance requirements. The wide temperature range supports direct integration into automotive under-hood or industrial heating systems without additional thermal management.

Pressure Sensors Transducers Part Context

This part belongs to the MLX90817 series of absolute pressure sensors manufactured by Melexis Technologies NV. The series is characterized by its ability to withstand aggressive chemical environments while maintaining precision. The DFN-14 package provides a compact footprint suitable for space-constrained board-mounted designs. The SP suffix typically denotes a sample or specific packaging variant distinct from the standard RE reel configuration.

Pressure Sensors Transducers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacements require matching the 14-BFDFN package, 4.5V-5.5V supply range, and harsh media compatibility. Verify pinout and electrical characteristics with alternative manufacturers before substitution.
