How Does The Magneto 6 Click Board™ Work?

The Magneto 6 Click Board™ uses the TLI493D-A2B6 IC, low power three dimensional Hall effect sensor with I2C interface, from Infineon. Within its small 6-pin package the sensor provides direct measurement of the X, Y, and Z components of a magnetic field. This sensor offers accurate three dimensional sensing with extremely low power consumption and consists of three main functional units:

• The power mode control system, containing a low-power oscillator, basic biasing, accurate restart, undervoltage detection, and a fast oscillator.
• The sensing unit, which contains the HALL biasing, HALL probes with multiplexers, and successive tracking ADC, as well as a temperature sensor.
• The I2C interface, containing the register files.

Some of the main characteristics of this sensor IC are 3D magnetic flux density sensing of ±160 mT, 12-bit data resolution for each measurement direction plus 10-bit temperature sensor, programmable flux resolution down to 65 μT, and interrupt signal to indicate a valid measurement to the microcontroller. For a good adaptation, this sensor is equipped with different modes and a digital communication interface. I2C interface can be accessed in any power mode. The interrupt function is multiplexed with the I2C SCL pin, and can be used to indicate measurement completion. The use of an interrupt line is optional but highly recommended to ensure proper and efficient readout of the sensor data. The Magneto 6 Click Board™ is ideally suited for the measurement of 3 dimensional movement within a magnetic field, linear slide movement, or 360° angle rotation. The magnetic measurement values are provided in the two's complement with 12-bit or 8-bit resolution in the registers with the symbols Bx, By, and Bz. By default, the temperature measurement is activated. The temperature measurement can be disabled if it is not needed and to increase the speed of the repetition of the magnetic values.

This Click Board™ uses I2C communication interface, and it's designed to be operated only with 3.3V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 5V. More information about the TLI493D-A2B6 can be found in the attached datasheet. The Magneto 6 Click Board™ comes equipped with a library that contains easy to use functions and a usage example that may be used as a reference for the development.
