3 Description

The TMAG5173-Q1 is a low-power linear 3D Halleffect

sensor designed for a wide range of automotive

applications. This device integrates three independent

Hall-effect sensors in the X, Y, and Z axes. A

precision analog signal-chain 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 communication with low-voltage 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 can be configured through the

I2C interface to enable any combination of magnetic

axes and temperature measurements. Additionally,

the device can be configured to various power

options (including wake-up and sleep mode) allowing

designers to optimize system power consumption

based on their system-level needs. 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 can also be used by a

microcontroller to trigger a new sensor conversion.

An integrated angle calculation engine (CORDIC)

provides full 360° angular position information for both

on-axis and off-axis angle measurement topologies.

The angle calculation is performed using two

user-selected magnetic axes. The device features

magnetic gain and offset correction to mitigate the

impact of system mechanical error sources.

The TMAG5173-Q1 is offered in four different factoryprogrammed

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.
