Firmenblog über Supplying BOSCH BMI325: A High-Performance Six-Axis IMU Sensor to Enhance Wearable and AIoT Applications

Abstract: Shenzhen Mingjiada Electronics Co., Ltd. (Mingjiada Electronics) announced that it is now offering large quantities of the BMI325, a high-end six-axis inertial measurement unit (IMU) from Bosch Sensortec. With its ultra-low power consumption, compact package, and high-precision sensing capabilities, this product is an ideal choice for applications such as TWS earbuds, smartwatches, AR/VR, and industrial motion tracking. As a globally renowned mixed-line distributor of electronic components, Mingjiada offers genuine, in-stock products, highly competitive pricing, and technical support services.

About the BOSCH BMI325: The Perfect Balance of Power Consumption and Performance

With the trend toward increasingly smaller and smarter consumer electronics, sensors no longer merely detect motion; they have become the core of intelligent device interaction. The BOSCH BMI325 is a landmark product in the Bosch MEMS sensor family. It integrates a three-axis accelerometer, a three-axis gyroscope, and a temperature sensor into a tiny 2.5×3.0×0.83mm LGA-14 package.

The following are the core technical advantages of the BMI325:

1. Ultra-low-power architecture for extended device battery life

Power consumption has always been a major challenge for wearable devices. The BMI325 features a built-in intelligent power management unit (PMU) that supports dynamic power switching.

High-performance mode: Typical current is only 790 μA (approximately 15% lower than the previous generation).

Low-power standby: Automatically enters standby mode when the device is stationary, with current as low as 15μA.

Fast startup: Accelerometer startup takes only 2.5ms, and gyroscope startup takes less than 1ms, enabling seamless wake-up.

2. High precision and measurement ranges to capture every movement

The BMI325 offers flexible and wide measurement range options, capable of capturing not only subtle tilts but also intense device movements:

Accelerometer Range: ±2g/±4g/±8g/±16g (programmable).

Gyroscope Range: ±125/±250/±500/±1000/±2000 dps (degrees per second).

Output Resolution: 16-bit ADC ensures high data accuracy and effectively suppresses temperature drift.

3. Rich Smart Features and Interfaces

To reduce the load on the microcontroller (MCU), the BMI325 is equipped with a 2KB FIFO buffer that supports batch processing of data. It features a wealth of “smart-out-of-the-box” functions, such as a pedometer, tilt detection, tap detection, and orientation detection, meaning it can recognize specific actions without waking the main system.

In addition to standard I²C and SPI interfaces, the chip supports the latest I³C high-speed interface, enabling lower power consumption and higher data throughput.
