LPS225HBTR

Pressure Sensors Transducers Overview

The LPS225HBTR is a piezoresistive absolute pressure sensor manufactured by STMicroelectronics, designed for digital output barometer applications. It features an ultra-compact monolithic sensing element integrated with an IC interface supporting I2C and SPI protocols. The device operates within a pressure range of 26 kPa to 126 kPa (3.77 PSI to 18.27 PSI) and provides a 24-bit digital resolution. It functions on a supply voltage between 1.7 V and 3.6 V, with a typical operating current of 4 µA. The sensor includes temperature compensation and is housed in an 8-WLGA package, suitable for surface mount installation.

Pressure Sensors Transducers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to storage and handling. Ensure ESD protection measures are implemented during assembly due to the sensitive MEMS structure. Cross-reference datasheet revisions to confirm pinout and electrical specifications match the specific production batch requirements.

Pressure Sensors Transducers Selection Notes

Select this component for applications demanding high accuracy in a minimal footprint. The 24-bit resolution supports precise atmospheric pressure detection. Consider the 8-WLGA package dimensions for PCB layout constraints. Evaluate the -40°C to +85°C operating temperature range against environmental conditions. Verify interface compatibility with the host microcontroller's available I2C or SPI ports before finalizing the design.

Pressure Sensors Transducers Part Context

This part belongs to the LPS225HB series of board-mount pressure sensors from STMicroelectronics. It is specifically engineered for low-power, space-constrained environments. The device complements other inertial measurement units and sensors in the company's portfolio, often used in conjunction with accelerometers and gyroscopes for navigation systems.

Pressure Sensors Transducers Replacement Considerations

The LPS22HBTR is documented as a substitute for the LPS225HBTR. Verify functional equivalence and pin compatibility before replacement. Note that the LPS225HBTR may be considered obsolete in some contexts; confirm current availability and lead times for both parts.
