3 Description
The TMAG5273 is a low-power linear 3D Hall-effect sensor designed for a wide range of industrial and personal electronics applications. This device integrates three independent Hall-effect sensors in the X, Y, and Z axes. A precision analog signalchain along with an integrated 12-bit ADC digitizes the measured analog magnetic field values. The I2C interface, while supporting multiple operating VCC ranges, ensures seamless data munication with low-voltage microcontrollers. The device has an integrated temperature sensor available for multiple system functions, such as thermal budget check or temperature pensation calculation for a given magnetic field.
The TMAG5273 can be configured through the I2C interface to enable any bination of magnetic axes and temperature measurements. Additionally, the device...
