ILPS28QSWTR

Pressure Sensors Transducers Overview

The ILPS28QSWTR is an automotive-grade, absolute digital output barometer manufactured by STMicroelectronics. It features a dual full-scale pressure range of 1260 hPa and 4060 hPa (approximately 3.77 PSI to 58.89 PSI), with a maximum pressure rating of 145 PSI. The device provides a 24-bit digital resolution and operates on a supply voltage between 1.7 V and 3.6 V. It utilizes I2C and I3C interfaces for data communication. The sensor is housed in a compact 6-CLGA package with exposed pads, measuring 2.8x2.8 mm. It includes temperature compensation and supports Qvar detection within a water-resistant package, functioning reliably across a temperature range of -40°C to 105°C.
