Pressure Sensors Transducers Procurement Notes

Verify the specific suffix configuration against project requirements, as variations in the MLX90809 series denote different pressure ranges and output types. Confirm that the SENT protocol implementation aligns with the target system's communication interface. Ensure the 16-SOIC package footprint matches the PCB layout, particularly regarding the exposed pad thermal connection. Check for any export restrictions or documentation requirements associated with this component before finalizing orders.

Pressure Sensors Transducers Selection Notes

Select this model when a digital SENT interface is required for differential pressure sensing in automotive environments. The wide temperature range and AEC-Q100 qualification make it suitable for under-the-hood applications. Consider the specific pressure span of -120 kPa to 5 kPa to ensure it covers the operational range without saturation. The exposed pad package requires careful thermal management during soldering to maintain reliability.

Pressure Sensors Transducers Part Context

This component belongs to the MLX90809 family of board-mount pressure sensors. The family integrates signal conditioning and digital processing on a single chip. Variants within the series differ primarily in pressure range, port style, and output type (analog vs. SENT). This specific part represents the differential pressure variant with digital output.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes include other MLX90809 variants with matching pressure ranges and SENT outputs, such as MLX90809LXG-EAD-000-RE for relative pressure applications if the interface remains compatible. Cross-referencing pinouts and mechanical dimensions is essential when considering alternative manufacturers.
