Off-Axis/On-Axis magnetic angle encoder


Description:

Mt6818 is a new generation of magnetic angle encoder IC developed by magntek, which is suitable for on axis and off axis applications. Based on anisotropic magnetoresistance (AMR) technology and proprietary signal processing technology, MT6818 can measure the absolute angle from 0 to 360 degrees. MT6818 can be adapted to one pair of pole or multi pole magnetic ring in off-axis application, and the width of magnetic pole can be freely selected (> 1 mm). With the rotation of magnetic field parallel to the chip surface, the chip will output the corresponding encoded angle signal. At the same time, users can also read the absolute angle data calculated inside the chip through the high-speed SPI interface.

MT6818 provides QFN3x3 package and can output ABZ, UVW, PWM and SPI signals at the same time. It is widely used in various consumer and industrial fields such as position feedback control and rotation control of various motors.


Features:

-Based on AMR technology, absolute angle measurement from 0 ° to 360 ° is provided

-Operating voltage 3.3 ~ 5.0V

-Operating temperature - 40 ℃ ~ 125 ℃

-Typical value of linearity deviation < ± 1.0 °

-Standard 4-wire SPI interface (maximum clock 16mHz) is provided to read 14 bit angle data 

-The incremental output ABZ supports any resolution of 1 ~ 1024 lines (each pair of magnetic poles)

-Incremental output UVW supports any pair of poles from 1 to 16 (each pair of magnetic poles)

-Provides 12 bit PWM output


Application: industrial robot joint, AGV (automatic guided transport vehicle), etc
