3 Description
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 is suitable for 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 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.
