TMAG5170D-Q1具有 SPI 接口的汽车类高精度 3D 线性霍尔效应双芯片传感器
The TMAG5170D-Q1 is a dual-die 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 TMAG5170D-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.
