具有精确线性位置检测的四通道 3D 霍尔效应传感器参考设计
TIDA-060045
概述
This reference design demonstrates precision, low-latency linear position sensing of a N45 magnet target using single or multiple equidistant placed 3D Hall-effect sensors TMAG5170 with high-speed 10MHz SPI interface, where the Z-axis and X-axis magnetic field strength as well as CRC data are transmitted in a single 32-bit frame for low latency and enhanced data integrity. The digital interface with 3.3V I/O is compatible to the C2000™ MCU Launchpad and enables evaluation of our 3D Hall-effect sensing technology with a C2000™, Sitara or other MCUs.
特性
- Single-chip 3D Hall-effect sensor with integrated ADC and SPI interface reduce BOM and PCB size.
- Linear position accuracy typically ±0.15mm over 100mm range using quad 3D Hall-effect sensors help achieve more precise linear position sensing systems.
- 3D Hall-effect sensors with configurable sensitivity ±25mT to ±100mT and ±75mT to ±300mT help adjust measurement range for better accuracy.
- Sample rates up to 8kHz, low latency of 57.5us and 10MHz SPI enable higher speed position control.
- Dedicated ALERT pin enables simultaneous start-of-conversion of X,Y,Z axis across multiple 3D Hall-effect sensors.
- 3D Hall-effect sensors diagnostics features help detect and report both system and device-level failures and simplify design for functional safety.
