Product Description
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 offers high accuracy (< 0.35 error) and ultra-low latency (1 s data updates). The sensor supports multiple output modes including programmable ABZ quadrature pulse output (up to 4096 steps/turn), SPI communication for angle reading and register access, 2-wire SSI output, and 14-bit PWM absolute position output. It features built-in magnetic field strength detection with programmable thresholds for monitoring and adjustment, and incorporates Memory-Programmable Technology (MPT) for storing configuration parameters like zero-angle position and ABZ encoder settings. The KTH7801 is suitable for applications requiring accurate angle measurement and speed control, including brushless DC motors, automotive angle control, closed-loop stepper motors, and barrier gates.
