KTH7812 16-bit High-Precision Low-Latency Hall Magnetic Encoder
The KTH7812 is a high-precision absolute angle Hall sensor chip offering up to 16-bit resolution for absolute angle output. It enables contactless magnetic field angle measurement in both on-axis and off-axis scenarios. With a rapid update rate of 1us, it accurately outputs angle information across a wide speed range (0-120000rpm), making it suitable for applications requiring precise angle measurement and speed control. The KTH7812 provides flexible output modes including programmable ABZ quadrature pulse output (up to 4096 steps/revolution) and programmable UVW incremental output (1-8 pole pairs). It also supports four-wire SPI communication for angle reading and register read/write operations. The integrated magnetic field strength detection function allows for programmable high and low thresholds for real-time monitoring. An on-chip MTP (Multi-Time Programmable) memory stores essential configuration parameters like zero angle position, ABZ encoder settings, and magnetic field detection thresholds for flexible configuration.
