Three-axis MEMS accelerometer - Xiaomi smart bracelet design

Overview

This document introduces the application and reference design of ADI ADXL362 (ADXL362 data sheet) three-axis MEMS accelerometer in Xiaomi smart bracelet solution. ADXL362 micro-power three-axis MEMS accelerometer (typical application of acceleration sensor). Digital output, acceleration range is ±2/±4/±8 g. The operating voltage is 1.8V-3.3V, the power consumption is 2μA at the power supply voltage of 2V and 100Hz output data rate, and the power consumption of motion-triggered wake-up mode is 300nA. The device provides 12-bit output resolution, 8-bit format data, and a resolution of 1 mg/LSB in the ±2 g range. It is mainly used in hearing aids, home health equipment, motion-enabled power switches, wireless sensors and motion-enabled metering equipment.
