The TMAG5170-Q1 is a high-precision linear 3D Hall-effect sensor designed for a wide range of automotive and industrial 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-Q1 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 dedicated ALERT 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.

The TMAG5170-Q1 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 ±25 mT to ±300 mT.

The device performs consistently across a wide ambient temperature range of –40°C to +150°C.
