InvenSense ICM-20789 High Performance 6-Axis Motion Sensor and Pressure Sensor Combo

——Reverse analysis report

The world's first 7-axis motion combination sensor, the target application is drone

According to Mamms Consulting, InvenSense, the leading provider of MEMS sensor platform solutions, has been Apple's 6-axis inertial measurement unit (IMU) supplier for many years. InvenSense has a large IMU market share, with its main competitors being Bosch and STMicroelectronics. With the acquisition of the Sensirion pressure sensor division, InvenSense has entered a new market segment. This year, InvenSense announced the mass production of its first and only 7-axis motion sensor, the ICM-20789.

The 7-axis motion sensor ICM-20789 integrates InvenSense's leading 6-axis (3-axis accelerometer + 3-axis gyroscope) MEMS motion sensor with its world-class air pressure sensor (altimeter) to provide the most advanced discretes available today. A comparable solution for sensor performance. InvenSense's 6-axis motion sensor has been successfully used in the drone market, including toys and commercial applications, with its reliable core performance and adaptability to the harsh environments faced by drones during different flight phases. . The ICM-20789 provides customers with an easy upgrade path by adding a relative pressure sensor based on capacitive technology, leading performance and excellent temperature stability on InvenSense's proven 6-axis motion sensor. The combination of its motion sensing and air pressure sensing performance is very necessary for most consumers in the toy drone market with limited flight control experience. For intelligent drones that need to maintain automatic stable cruise. It is also very important, for example, to help achieve tracking video capture of users.

InvenSense Motion Combination Sensor ICM-20789 Package Size The professional drone market is already leveraging the advantages of air pressure sensors to simplify drone takeoff and landing, and also provides stable hover by using discrete 6-axis motion sensors and air pressure sensors mode. The ICM-20789, combined with InvenSense's drone fusion software for the professional drone market, brings the stability of professional-grade drones to the toy and smart drone market. With precise take-off and lift control, the toy drone will no longer rush to the ceiling of the room, fall on the roof, or hit the tree outside, and will be able to safely return to the user's hand, bringing the user Come for more flying fun. This report provides detailed disassembly and reverse analysis of the InvenSense motion combination sensor ICM-20789, both in terms of technology and cost, and also compares it with other 6-axis IMUs.
