Product Overview
The KTH7801 is a high-precision 16-bit absolute angle Hall sensor chip designed for non-contact angle measurements in both on-axis and off-axis configurations. It supports a wide range of rotational speeds (0-120,000 rpm) and offers multiple output modes including programmable ABZ quadrature pulse output (up to 4096 steps/turn), 4-wire SPI, 2-wire SSI, and 14-bit PWM angle output. The sensor features built-in magnetic field strength detection with programmable thresholds for monitoring and adjustment, and incorporates Memory-Programmable Technology (MPT) for storing critical configuration parameters like zero-angle position and ABZ encoder settings. Its ultra-low latency (1 s data updates) and AEC-Q100 qualification make it suitable for demanding applications.
