The TMAG5170-Q1 IC is based on the
Hall-effect technology and precision mixed signal
circuitry from Texas Instruments. The output
signals (raw X, Y, Z Magnetic data and Die
temperature data) is provided through the SPI. The
device can be configured in multiple settings
through user access registers through the SPI.
The IC consists of the following functional and building blocks:
- The Power Management & Oscillator block
contains a low-power oscillator, biasing circuitry, undervoltage and
overvoltage detection circuitry, and a fast oscillator.
- The sensing and temperature measurement block
contains the Hall biasing, Hall sensors with multiplexers, noise filters,
integrator circuit, temperature sensor, and the ADC. The Hall sensor data
and temperature data are multiplexed through the same ADC.
- The Interface block contains the SPI control
circuitry, ESD protection circuits, and all the I/O circuits. The TMAG5170-Q1 supports SPI along with integrated cyclic
redundancy check (CRC).
- The diagnostic blocks are embedded in the circuitry to enable mandatory and user-enabled diagnostic checks.
