Product Description
Product Overview
The ATS17501 is a single IC solution for rotational position sensing in automotive and industrial electric motor applications. It features three Hall elements for two independent differential channels, processing inputs with digital circuits and robust algorithms to eliminate offsets and false transitions. The IC provides highly accurate speed and direction information, with advanced calibration for consistent switch points over air gap, speed, and temperature. It is programmable for various applications and can be configured for Fault Detection mode for ASIL B(D) utilization. The SG package is a lead-free 4-pin SIP with an integrated back-biasing magnet.
