ICM-45686 ICM-45686 TDK InvenSense 6-Axis MEMS MotionTracking Sensor

The ICM-45686 is a high-precision 6-axis MEMS MotionTracking® device from TDK InvenSense, integrating a 3-axis gyroscope and 3-axis accelerometer for accurate motion sensing in compact, power-sensitive designs. It belongs to TDK’s ultra high-performance 6-axis MEMS motion sensor family and features the company’s BalancedGyro™ technology, designed to deliver strong motion performance with low power consumption.

With 6-axis current consumption of 0.42 mA in Low Noise mode and 0.22 mA in Low Power mode, the ICM-45686 is suitable for battery-powered applications that require reliable motion detection, orientation tracking, gesture recognition, and event-triggered wake functions.

The device supports a wide range of embedded APEX motion functions, including pedometer, tilt detection, single/double tap detection, raise-to-wake, wake-on-motion, free-fall detection, significant motion detection, low-G detection, and high-G detection. These features help reduce host processor workload and enable responsive motion-based user experiences in wearables, hearables, AR/VR devices, controllers, drones, and robotics systems.

Key Features

Product Description

The TDK InvenSense ICM-45686 is designed for applications that require precise, low-power inertial sensing in a compact package. Combining a high-performance gyroscope and accelerometer, it enables motion tracking, gesture detection, activity recognition, stabilization, and system wake-up functions for modern consumer and embedded electronics.

Its Balanced Gyroscope Architecture supports improved motion performance, while low 6-axis operating current helps extend battery life in wearable and portable devices. The sensor also includes FIFO Data Rate (FDR) support, allowing systems to optimize data handling and reduce overall power consumption.

For designs that need high dynamic range, the ICM-45686 provides gyroscope full-scale range up to ±4000 dps and accelerometer full-scale range up to ±32 g, making it suitable not only for wearable motion tracking but also for gaming controllers, drones, flight controllers, robotics, and AR/VR devices.
