Texas Instruments TMAG5173-Q1 Automotive 3D Hall-Effect Sensors

Texas Instruments TMAG5173-Q1 Automotive 3D Hall-Effect Sensors are developed for various automotive and industrial applications. The TMAG5173-Q1 incorporates three independent Hall-effect sensors in the X, Y, and Z axes.

The TI TMAG5173-Q1 Sensors feature a precision analog signal chain that facilitates applications requiring narrow design tolerance. Integrated safety mechanisms allow a robust, functional, and safe system design. The sensors are ideal for 1D linear measurements, 2D angle measurements, 3D joystick measurements, magnetic threshold cross detection, and diverse user-configurable switch function applications. The digital filter option allows up to 32 times sensor data integration for improved noise performance. The I²C interface, while supporting multiple operating V_CC ranges, provides seamless data communication with microcontrollers.

The TMAG5173-Q1 has an integrated temperature sensor for multiple system functions, such as thermal budget check or temperature compensation calculation for a given magnetic field.
