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 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 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.

TIDA-060040 — 具備用於精確馬達位置控制之霍爾效應感測器的絕對角度編碼器參考設計

TIDA-060040 參考設計展示了精密馬達控制應用 (例如機器手臂控制) 中典型的絕對角度編碼方法。角度編碼可利用各種磁感技術加以實現。這是透過檢測兩個自然異相 90° 的磁通量密度、B 場向量分量來完成的。磁鐵旋轉時,感測器輸入為正弦,因此能使用三角函數屬性進行計算。

然而由於系統的電氣和機械特性,通常需要修正最終結果以達到最高準確度。一般而言,在大多數精密度馬達控制應用中,最終目標誤差要小於 0.1°。此設計探索了選擇磁鐵、決定放置與修正系統層級缺陷的過程,以實現高準確度的角度量測。
