Magnetic field sensor for battery powered applications
The MLX90397 brings the Triaxis® Hall magnetic-sensing technology to cost-conscious white goods, smart metering, gaming & home-security sectors. Low power and wide voltage supply 3D magnetic field sensor IC enables maximum flexibility on the choice of the battery.
The MLX90397 is a 3D magnetometer designed for position sensor applications with a +/-50 mT range with an adaptive range on BZ of +/-200 mT. It makes it ideal for battery-powered applications.
Design
The device, especially designed for micropower battery powered applications, measures magnetic fields along the 3 axis X, ,Y and Z (Y being in a plane parallel to the surface of the die, Z being perpendicular to the surface).
