The I2C interface, while supporting multiple operating VCC ranges, ensures seamless data communication with low-voltage microcontrollers. The TMAG5273 features an integrated temperature sensor available for numerous system functions, such as thermal budget check or temperature compensation calculation for a given magnetic field.
The TI TMAG5273 can be configured through the I2C interface to enable any combination of magnetic axes and temperature measurements. Furthermore, the sensors can be configured to various power options (including wake-up and sleep mode), allowing users to optimize system power consumption based on the system-level needs.
The device offers multiple sensor conversion schemes, and I2C read frames help optimize throughput and accuracy. A dedicated INT pin can act as a system interrupt during low power wake-up and sleep mode and be used by a microcontroller to trigger a new sensor conversion. An integrated angle calculation engine (CORDIC) provides full 360° angular position information for on-axis and off-axis angle measurement topologies. The angle calculation is conducted using two user-selected magnetic axes. The TMAG5273 features magnetic gain and offsets correction to mitigate the impact of system mechanical error sources.
The TMAG5273 is available in four different factory-programmed I2C addresses. The device also supports additional I2C addresses by modifying a user-configurable I2C address register. Each orderable part can be configured to select one of two magnetic field ranges that fit the magnet strength and component placement during system calibration.
The TMAG5273 performs consistently across a wide ambient temperature range of –40°C to +125°C and is housed in a DBV package.
