ICM-42607 High-Performance Six-Axis IMU – Core Solution for UAV Flight Control and Attitude Sensing | Mingjiada Electronics Supply and Recycling

I. ICM-42607 Product Overview

The ICM-42607 is a high-performance six-axis MEMS MotionTracking™ Inertial Measurement Unit (IMU) launched by TDK InvenSense, which integrates three high-precision gyroscopes and three high-linearity accelerometers onto a single chip. Designed specifically for high-end consumer and industrial drones, this chip offers key advantages such as low noise, low temperature drift, low power consumption and high dynamic response. It is perfectly suited to the flight control requirements of multirotor drones, racing drones and small inspection drones, making it the preferred solution for attitude sensing systems in small and medium-sized drones.

The chip utilises an ultra-compact 14-pin LGA package, measuring just 2.5 mm × 3.0 mm × 0.76 mm. Its extremely small form factor significantly saves space on the drone’s onboard PCB, meeting the hardware design requirements for lightweight and compact drones, whilst effectively reducing the overall weight of the aircraft and enhancing the drone’s flight endurance and manoeuvrability.

II. ICM-42607 Key Advantages

1. Industry-leading ultra-low noise

The ICM-42607 offers the lowest gyroscope and accelerometer sensor noise among IMUs of its kind:

Gyroscope noise: typically as low as 7 mdps/√Hz

Accelerometer noise: typically as low as 100 μg/√Hz

These ultra-low-noise characteristics significantly reduce the filtering burden on post-processing algorithms, improve attitude estimation accuracy, and enable smoother drone flight.

2. Outstanding Stability and Interference Resistance

Shock resistance: Withstands impacts of up to 20,000g

Vibration resistance: Effectively suppresses noise caused by out-of-band vibrations, coping with the high-frequency vibration environment of drone motors

Temperature stability: Gyroscope zero-bias temperature drift is only ±0.015 dps/°C, whilst the accelerometer’s zero-bias temperature drift is ±0.15 mg/°C; the operating temperature range spans from –40 °C to +85 °C, with exceptionally stable sensor data across the entire temperature range

3. Ultra-low power consumption design

Power consumption during six-axis operation in low-noise mode is just 0.55 mA

Standby current as low as 3.5 μA

Supports ultra-low-power motion wake-up functionality to minimise system power consumption

4. Extensive Programmable Features

User-programmable full-scale range: the gyroscope supports ±250/±500/±1000/±2000 dps, whilst the accelerometer supports ±2/±4/±8/±16 g

Output resolution: 16-bit

Programmable digital filters: Supports user-programmable digital filtering for the gyroscope, accelerometer and temperature sensor

APEX motion processing engine: Built-in motion functions including pedometer, tilt detection, low-gravity detection, free-fall detection, motion wake-up and significant motion detection

IV. Advantages for Drone Applications

In drone flight control systems, the IMU is the core component for attitude estimation, stable hovering and precise navigation; its accuracy, stability, power consumption and immunity to interference directly determine the flight safety and control experience of the drone.

Specialised optimisations of the ICM-42607 for drone applications:

High-speed dynamic response: The gyroscope has a full-scale range of up to ±2000°/s, perfectly suited to the high-angle attitude changes encountered during high-speed rolls and rapid turns in racing drones, with no data clipping or dynamic distortion

Precise overload detection: The accelerometer accurately captures dynamic overload changes during drone take-off, landing, rapid acceleration and sudden deceleration

Vibration immunity: Effectively suppresses sensor noise caused by motor vibrations and airflow disturbances during flight, significantly improving attitude calculation accuracy

Low power consumption and long battery life: Operating current is only 0.65 mA in 100 Hz standard flight monitoring mode, reducing the system’s power consumption by over 30 per cent compared to traditional six-axis IMUs

Multi-sensor fusion: Supports externally triggered synchronous data acquisition from multiple sensors, precisely matching data from peripherals such as GPS, barometers and magnetometers
