Description
AI
The TMAG5170 is a high-precision linear 3D Hall-effect sensor designed for a wide range of industrial and personal electronics applications. The high level of integration offers flexibility and accuracy in a variety of position sensing systems. This device features 3 independent Hall sensors at X, Y, and Z axes.
A precision signal-chain along with an integrated 12-bit ADC enables high accuracy and low drift magnetic field measurements while supporting a sampling of up to 20 ksps. On-chip temperature sensor data is available for system-level drift compensation.
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 TMAG5170 can be configured through the SPI to enable any combination of magnetic axes and temperature measurements. Multiple sensor conversion schemes and SPI read frames help optimize throughput and accuracy. A dedicatedALERTpin 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.
The TMAG5170 offers multiple diagnostics features to detect and report both system and device-level failures. The SPI communication features a user-enabled cyclic redundancy check to enhance the data integrity.
The device is offered in two different orderables to support wide magnetic fields ranges from ±25mT to ±300mT.
The device performs consistently across a wide ambient temperature range of –40°C to +150°C.
