Triaxis micro-power magnetometers and evaluation board

Mouser is now stocking the MLX90393 Triaxis micro-power magnetometers and EVB90393 evaluation board from Melexis. The MLX90393 magnetometer is a fully-programmable and extremely compact sensor IC designed for low-power applications. The EVB90393 evaluation board offers engineers a platform for constructing a wide variety of highly-sophisticated human machine interfaces using the MLX90393 magnetometer. The magnetometer / evaluation board accurately measure changes in magnetic flux density along the X, Y, and Z axes using the Hall coefficient and Melexis’ patented Triaxis technology. The MLX90393 magnetometer is a highly-flexible 3mm × 3mm sensor designed for micro-power (2.2V - 3.5V, 5µA) applications, with programmable duty cycles from 0.1 percent to 100 percent. The chip features on-board non-volatile memory to store calibration data on-chip. The sensor can interchange measurement speed for both current consumption and noise on the digital output signal, making it a versatile building block for diverse magnetic sensing application The 30mm × 30mm EVB90393 evaluation board supports both SPI and I2C protocols for easy integration with an external microcontroller. The board incorporates a pad for connecting a decoupling capacitor, if required, as well as pads for optional pull-up and pull-down resistors for I2C addressing and bus line supply. The board is optimized for more complex 3D sensing systems, such as joysticks or rotary knobs with push functions.
