MT6709：Magnetic Encoded Chips - Off-axis magnetic angle encoded ICs
>
MT6709 is a new generation of decoding chip launched by MagnTek Microelectronics for angle calculation of sine and cosine analog signals input from external linear Hall (working with 1 pair of pole magnetic rings). As the rotation shaft drives the rotation of a single pair of pole magnetic rings (one N pole, one S level), four linear Hall chips placed at 90 degrees around the magnetic rings will induce the output of positive and cosine analog signals, and MT6709 can obtain absolute angle data with a resolution of 17 bits after compensating, calculating and decoding the four differential positive and cosine analog input signals; The angular data is further encoded into a maximum resolution of 2,500 pulses/cycle or 10,000 steps/cycle in AB increments; The MT6709 also provides a UVW output with a resolution of 1~63 poles/cycle. The MT6709 provides a 3-wire SPI interface for the host computer or MCU to read the 17-bit absolute angle data inside the chip. At the same time, the PWM with a single-line output can also provide angle data with a resolution of 12 bits. The STATUS and FAULT interrupt pins will output some working status and diagnostic information of the chip in real time. The core advantage of the MT6709 is that it provides a simple self-calibration mode on the user side. Users do not need to interact with the MT6709 chip, do not need to reference the source, and only need to move for a few cycles to compensate for the misalignment, amplitude and phase errors of the external input sine and cosine signals.
