The MT6813 is MagnTek's second-generation angle encoder chip, which is based on anisotropic magnetoresistive (AMR) technology and proprietary signal processing technology to achieve absolute angle measurement of 0~360°. The chip consists of a pair of AMR Wheatstone bridges and signal processing ASIC circuits. As the magnetic field parallel to the surface of the chip rotates, the chip outputs a corresponding encoded angle signal, and the user can also read the angle data calculated inside the chip via the I²C/SPI interface. Compared with traditional Hall sensors, AMR angle sensors are easier for customers to install because they operate in the saturation zone, which reduces the magnetic field requirements. The MT6813 is available in SOP-8 and QFN-16 packages, making it suitable for a wide range of consumer and industrial applications, including position feedback control and rotation control of various motors.
