A17501数据手册传感器变送器的位置传感器-角度、线性位置测量规格书PDF

描述 Description

The A17501 is a single IC solution designed for rotational position sensing of a ring magnet target found in automotive and industrial electric motor applications (often with specific application and safety requirements).

Three Hall elements are incorporated to create two independent differential channels. These inputs are processed by digital circuits and robust algorithms designed to eliminate the detrimental effects of magnetic and system offsets, and to address false output transitions caused by target vibrations in electric motors at startup and low speed operation. The differential signals are used to produce a highly accurate speed output and, if desired, provide information on the direction of rotation. 

Advanced calibration techniques are used to optimize signal offset and amplitude. This calibration, combined with the digital tracking of the signal, results in accurate switch points over air gap, speed, and temperature. 

The IC can be programmed for a variety of applications requiring dual-phase target speed and position signal information or simultaneous high-resolution target speed and direction information. It can be configured to enable Fault Detection mode for ASIL B(D) utilization.
