Melexis launched a compact low -voltage 3D magnetometer for consumer applications

     Melexis announced the launch of the three -axis magnetic field sensor chip MLX90392 facing white home appliances, consumer electronics products and smart instrument applications, which can share 1.8V power rails with other components (such as logic devices).

     MLX90392 is low -cost and does not require dedicated LDO or regulator. It simplifies the design while reducing the cost of material lists and saving PCB space. The sensor chip is encapsulated with UTDFN-8 ultra-thin and non-lead 8 pins, with a size of only 2 mm x 2.5 mm x 0.4 mm, which is convenient for designers to meet the application requirements of limited space. In addition, the power -saving model of 1.5 省A helps energy saving, maximizing the running time in battery power supply applications.

     MLX90392 integrates temperature sensors and uses an i2C communication protocol, which can provide 16 -bit position measurement values (using x, y, Z coordinate) and temperature values on the I2C bus with a working frequency of up to 1 MHz. There are two models of the sensor chip, which can choose ± 50 mt and ± 5 mt full range, and use Melexis to win patented Triaxis Hall technology to achieve low noise and ultra -high precision.

     ± 50 MT range is most suitable for location measurement in HMI applications, closes check detection in white appliances and access control systems, intelligent instrumental tampering, and non -contact manipulating rods (this type of manipulating rod compared to the traditional potential location sensing scheme can save savings. Power consumption). For the position detection of a small magnetic field range and the precise position measurement of the noise as a key design parameter, the sensitivity of the ± 5 mt model can reach 0.15 µT/LSB and the typical RMS noise is as low as 0.3 µt. Both models support a single measurement and continuous measurement mode, which is very design flexibility. Self -inspection status, data ready, and magnetic sensor overflow instructions can provide a full range of diagnosis.
