STMicroelectronics, Inc. Motion Sensor ICs MIS2DHTR

The MEMS Digital Output Motion Sensor, part number 54AH6348, is an ultra-low-power, high-performance 3-axis accelerometer designed for various applications, particularly in medical and healthcare settings. It operates within a supply voltage range of 1.71 V to 3.6 V and features an independent IO supply of 1.8 V. The sensor supports selectable full scales of ¬±2g, ¬±4g, ¬±8g, and ¬±16g, with output data rates ranging from 1 Hz to 5.3 kHz. This device includes a digital I2C/SPI interface, three operating modes (low-power, normal, and high-resolution), and two independent programmable interrupt generators for free-fall and motion detection. It also offers 6D/4D orientation detection, embedded FIFO, self-test capabilities, and an embedded temperature sensor. The sensor is compliant with ECOPACK¬Æ and RoHS standards, ensuring it meets environmental regulations. The MIS2DH is suitable for applications such as activity monitoring, posture detection, remote patient monitoring, and general motion-activated functions in the medical domain. It is packaged in a compact LGA-12 form factor, measuring 2.0 x 2.0 x 1 mm, and is rated for operation over an extended temperature range of -40 ¬8C to +85 ¬8C.
