The TMAG5173-Q1 is a low-power linear 3D Hall-effect sensor designed for a wide range of automotive and industrial applications. This device integrates three independent Hall-effect sensors in the X, Y, and Z axes. A precision analog signal-chain supports applications requiring narrow design tolerance. Integrated safety mechanisms enable robust functional safe system design. The device can be used in 1D linear measurements, 2D angle measurements, 3D joystick measurements, magnetic threshold cross detection, and various 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 VCC ranges, ensures seamless data communication with microcontrollers. The device has an integrated temperature sensor available for multiple system functions, such as thermal budget check or temperature compensation calculation for a given magnetic field.
The TMAG5173-Q1 supports multiple operating modes (including wake-up and sleep mode) to optimize the system power consumptions and operating speed. During the active mode the device performs continuous conversions autonomously. During standby mode the INT pin or I2C communication can be used by a microcontroller to trigger a new conversion. During the sleep mode the device consumes ultra-low power and retains the configuration register values.
An integrated angle calculation engine (CORDIC) provides full 360° angular position information for both on-axis and off-axis topologies with an angle resolution of 1/16 degree. The angle calculation is performed for any of the X-Y, Y-Z, or Z-X planes based off the user configuration register selection. The device features magnetic gain and offset correction to mitigate the impact of system mechanical error sources.
The TMAG5173-Q1 can be configured through the user registers to enable any combination of magnetic axes and temperature channel conversions. The device supports several I2C read frames along with cyclic redundancy check and diagnostic status communications.
The TMAG5173-Q1 is offered in four different factory-programmed I2C addresses. The device also supports additional I2C addresses through the modification of a user-configurable I2C address register. Each orderable part can be configured to select one of two magnetic field ranges that suits the magnet strength and component placement during system calibration.
The device performs consistently across a wide ambient temperature range of –40°C to +125°C.
