Product Overview
The TMAG5273 is a Texas Instruments low-power linear 3D Hall-effect sensor. It integrates X, Y, and Z Hall-effect sensors with a 12-bit ADC that digitizes measured magnetic field values and communicates through an I2C digital interface. The I2C interface supports up to 1 MHz and includes CRC per the extracted datasheet facts.
The device operates from a recommended 1.7 V to 3.6 V supply and across -40°C to +125°C free-air temperature. Orderable variants provide selectable magnetic ranges of ±40 mT and ±80 mT for TMAG5273x1 devices, and ±133 mT and ±266 mT for TMAG5273x2 devices. A1/B1/C1/D1 data includes ±40 mT and ±80 mT linear ranges with sensitivities of 820 LSB/mT and 410 LSB/mT.
