Magnetic Encoding IC-Low Speed Magnetic Angle Encoding IC

Description:

MT6815 is the second-generation angle encoder chip introduced by MagnTek, based on anisotropic magnetoresistance (AMR) technology and proprietary signal processing technology to achieve 0-360° absolute angle measurement. 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 will output the corresponding encoded angle signal. At the same time, the user can read the angle data calculated inside the chip through the I²C/SPI interface. Compared with the traditional Hall sensor, the AMR angle sensor works in the saturation zone, which reduces the requirement on the magnetic field, making it easier for customers to install. MT6815 is available in SOP-8 and QFN-16 packages, and is widely used in various consumer and industrial fields such as motor position feedback control and rotation control.
