MEMS pressure sensor enhances measurement accuracy

The LPS22HH MEMS piezoelectric absolute pressure sensor is so accurate and stable, according to STMicroelectronics, that manufacturers can eliminate one-point calibration (OPC) after soldering to increase throughput and efficiency.

With a pressure noise equivalent to 5cm, the LPS22HH enhances controls such as collision avoidance for drones or other unmanned vehicles. Its superior accuracy also enhances features of smartphones and sport watches, such as indoor navigation.

In addition, temperature compensation is built in, relieving the load on the host microcontroller or application processor, helping to save energy and ensure smooth operation across the full temperature range. High stability over wide-ranging operating conditions also boosts the performance of devices such as gas meters, weather-station equipment and wearables.

The LPS22HH leverages ST’s latest advancements both in MEMS structures and the controlling ASIC to achieve performance gains and the proven fully molded package technology, with miniaturized apertures that prevent particle contamination, ensuring excellent reliability.

Energy-conscious features include a 0.9µA power-down mode and low active power, drawing just 4µA at 1Hz, including temperature compensation, to maximize battery runtimes. Support for I2C, SPI, and MIPI I3CSM 2-wire sensor-bus interface provides flexible digital connectivity, and there is a generous 128-bit FIFO for storing sensor data to minimise host intervention.

The LPS22HH is in production now, packaged as a 2mm x 2mm x 0.3mm 10-lead HLGA
