HOW DOES IT WORK?
LIN Hall 2 Click is based on the TMAG5253, a low-power linear Hall-effect sensor from Texas Instruments. This device uses a ratiometric architecture to eliminate errors from VCC tolerance, as the external analog-to-digital converter (ADC) uses the same VCC for its reference. Additionally, the device features magnet temperature compensation for NdFeB and Ferrite to counteract the magnetic sensitivity drifts across a wide temperature range. It fully integrates the signal conditioning, temperature compensation circuits, mechanical stress cancellation, and output driver. The TMAG5253 is sensitive to the magnetic field component perpendicular to the sensor's top side. It also has a bipolar sensitivity where the north and south magnetic poles produce unique output voltages.
LIN Hall 2 Click uses an analog-to-digital converter (ADC) of the host MCU to read the analog values of the TMAG5253. The enable EN pin allows you to put the device in an ultra-low power (nA) mode when needed.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
