SC7U22TH-士兰微电子英文官网

The SC7U22TH is a inertial measurement unit (IMU) with high sensitivity and low power dissipation, featuring three-axis accelerometer and three-axis gyroscope .It has full scale acceleration range of ±2g/±4g/±8g/±16G, and the angular rate range of ±125/±250/±500/±1000/±2000dps. Users can flexibly measure external acceleration and angular velocity. The output data rate of the accelerometer can be selected from 0.78HZ to 1.6KHZ, and the output data rate of the gyroscope can be selected from 25HZ to 3.2KHZ. The normal operating temperature range is - 40°C to +85°C.

The IC communicates with the MCU through the I²C/SPI interface. The measurement data of the accelerometer and gyroscope can be obtained either through the interrupt mode or the polling mode. The INT1 and INT2 interrupt pins provide a variety of internally auto - detected interrupt signals, which are suitable for various motion - detection scenarios. These signals can effectively and reliably achieve functions such as motion detection, attitude positioning, and gesture recognition under the condition of extremely low system power dissipation. The interrupt sources include 6D/4D direction - detection interrupt signals, free - fall detection interrupt signals, sleep - and - wake - up detection interrupt signals, single - click and multi - click detection interrupt signals, step - counting function interrupt signals, hand - raising function interrupt signals, OIS function interrupt signals, and temperature - detection interrupt signals.

The IC is equipped with a high - precision calibration module and an internal LDO circuit. This ensures more stable zero - bias under different voltages and enables precise compensation for the offset and gain errors of the sensor. The built-in self-test function allows the customer to detect system functions during system testing, eliminating complex turntable testing.

SC7U22TH can be applied in smartphones, drones, game controllers, various Internet of Things and smart hardware systems. It supports mainstream operating systems, enables WeChat step - counting and gesture - based screen capture. Additionally, it provides algorithm support for drones, game controllers, VR and AR.
