The output signals (raw X, Y, Z Magnetic data and Die temperature data) is provided through the SPI interface. The device can be configured in multiple settings through user access registers through the SPI interface. The IC consists of the following functional and building blocks: • The power mode control system supports one VCC rail, containing a low-power oscillator, basic biasing, accurate reset, undervoltage, overvoltage detection, and a fast oscillator. • The sensing and temperature measurement block contains the HALL biasing, HALL probes with multiplexers, noise filters, temperature sensor, and ADC. The Hall sensor data and temperature data are multiplexed through the same ADC • The SPI interface, containing the register files and I/O pads. The TMAG5170-Q1 supports SPI interface along with integrated cyclic redundancy check (CRC). • The safety block is embedded in the circuitry to enable mandatory and user enabled safety checks. 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 Magnetic Flux Direction The TMAG5170-Q1 is sensitive to the magnetic field component in X, Y, and Z directions. The X and Y fields are in plane with the package. The Z filed is perpendicular to the top of the package. The device is sensitive to both magnetic north and south poles in each axis. As shown in Figure 2, the device will generate positive ADC codes in response to a magnetic south pole in the proximity. Similarly, the device will generate negative ADC codes if magnetic north poles approach from the same directions. |
