ILPS22QS Dual Full-Scale Pressure Sensor

STMicroelectronics' ILPS22QS is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer, supporting dual full-scale up to user-selectable 4,060 hPa. The device provides lower power consumption, achieving lower pressure noise than its predecessor. The ILPS22QS comprises a sensing element and an IC interface that communicates over I²C, MIPI I3C^SM, or SPI interfaces from the sensing element to the application. It supports a 1.2 V digital interface as well. The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process developed by ST.

The ILPS22QS embeds an analog hub sensing functionality to connect an analog input and convert it to a digital signal for embedded processing. Furthermore, embedded Qvar™ (electric charge variation detection) enables sensing in applications like water leakage detection, tap, double-tap, long press, and L/R - R/L swipe.

The ILPS22QS is available in a full-mold, HLGA (holed LGA) package. The package is holed to allow external pressure to reach the sensing element. It is guaranteed to operate over a temperature range extending from -40°C to +105°C.
