Following 10 days ago, Shendi Semiconductor released a single-axis automotive-grade MEMS gyroscope product, and Shendi re-magnetic sensor. In this way, the company's product line has covered three-axis consumer-grade, single-axis automotive-grade MEMS gyroscopes and three-axis MEMS magnetic sensors, and further built a deep six-axis, nine-axis sensor solution.

The main application areas of MEMS magnetic sensors include electronic compass, bit-based services and GPS blind spot-assisted positioning, which are widely used in smartphones, tablets, game controllers and GPS navigation devices. ST480MQ is mainly for mobile phones, tablets and other mobile terminal markets.

Due to the increasingly popular size of consumer terminals, the size, integration and reliability of MEMS sensors are becoming more and more stringent, and multi-sensor fusion solutions are also inevitable. After the introduction of the ST480MQ, the company's self-made products have covered gyroscopes and magnetic sensors, moving forward to the six-axis and nine-axis inertial combination solutions.

- Hall's technical advantage

The adoption of Hall technology is the development direction of the current mainstream MEMS magnetic sensor. Hall technology magnetic sensors have the advantages of small size, low power consumption, low cost, and simple interface circuit, which is especially suitable for the measurement of strong magnetic fields. At the same time, the use of magnetic collector (IMC) technology can largely compensate for the weakness of the Hall sensor, sensitivity, measurement accuracy and response time can be greatly improved, and enhance the function of the on-chip processing circuit, fully meet the needs of consumer electronics .

Another great advantage of Hall technology is that it can integrate magnetic sensor components and ASICs on the same chip, enabling a single-chip solution that takes advantage of single-chip, high integration, high reliability, ultra-small package, and low cost. Single-chip solutions are not yet possible with anisotropic magnetoresistance (ARM).
