MMA7360LR2 Application Field and Working Principle

MMA7360LR2, manufactured by Freescale Semiconductor, is a low-power, low-noise three-axis accelerometer designed for use in consumer electronic products. As one of the Motion Sensors - Accelerometers, this product is highly reliable and suitable for applications such as tilt sensing, navigation, vibration measurements, motor control, among many others.

Application Field

The MMA7360LR2 offers an integrated, low-power, low-noise three-axis accelerometer with a wide dynamic range of ± 2.7g. It is designed to work with microcontrollers using the I2C or SPI protocol, and uses a bi-directional, synchronous, interrupt-driven interface. The accelerometer is perfect for applications where power consumption, low noise, and high reliability are required. It has a wide range of applications in industrial, automotive, consumer electronics, navigation, gaming, medical, etc. It is widely used in tilt-sensing, motion-sensing, impact-sensing, vibration-measurement, motor control, and general user interface applications.

Working Principle

The MMA7360LR2 uses a capacitive sensing principle to measure acceleration. It contains a 3-axis X, Y, and Z piezoelectric accelerometer, which uses a pair of plates with a capacitor structure. As the accelerometer moves, the strain caused by movement sends an output signal proportional to the acceleration of the device. The signal is measured by a capacitive sensing circuit that processes the signal and sends it to the microcontroller. The onboard processor then processes the signal and produces an output that represents the acceleration value.

The accelerometer is designed with a 16-bit digital output and a wide dynamic range of ± 2.7 g. This gives it a high level of accuracy for applications that require precise measurements. The accelerometer also features a low power consumption, a low noise output, a temperature range of -40° C to +85° C, and a long-term reliability rating of 90%.

Conclusion

The MMA7360LR2, manufactured by Freescale Semiconductor, is a highly reliable, low-power, low-noise three-axis accelerometer designed for use in consumer electronic products. It offers an integrated, low-power, low-noise three-axis accelerometer with a 16-bit digital output and a wide dynamic range of ± 2.7g. It is suitable for applications such as tilt sensing, motion sensing, impact sensing, vibration measurement, motor control, and general user interface applications.
