SC69401HS

High Accuracy Magnetic Angle Sensor IC

differential Hall、Output modes: Analog, PWM, SPI

The SC69401 is an angular position sensor chip based on the principle of differential Hall magnetic sensing from Semiment Electronics. A full differential Hall sensing matrix is built into the center of the chip, which generates a corresponding sine-cosine position signal by sensing a pair of polar S/N magnets above it. The signal is amplified by a preamplifier and then sampled by the internal analog-to-digital converter circuitry. The chip's proprietary DSP circuitry performs angular arithmetic, and finally outputs the absolute position information (0-360 degrees) of the magnet's rotation in a variety of interface formats.
