Description

MT6828 Magnetic Encoder Chip 1~1024ABZ.1~16 Pole UVW14 Bit Off-axis Magnetic Encoder

Product Model: MT6828 (MT6818 upgrade version)

Manufacturer: MagnTek

describe:

MT6818 is a new generation of magnetic angle encoder chips introduced by MagnTek that is suitable for both on-axis (On-Axis) applications and off-axis (Off-Axis) applications. It is based on anisotropic magnetoresistive (AMR) technology and proprietary The signal processing technology realizes the absolute angle measurement of 0~360°. MT6818 can be adapted to one pair of poles or multiple pairs of pole magnetic rings in off-axis applications. The width of the magnetic poles can be freely selected (>1mm). With the rotation of the magnetic field parallel to the surface of the chip, the chip will output the corresponding encoded angle signal At the same time, the user can also read the absolute angle data calculated inside the chip through the high-speed SPI interface.

MT6818 is available in 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 motor position feedback control and rotation control.

feature:

– Based on AMR technology, it provides absolute angle measurement from 0° to 360°

– Working voltage 3.3~5.0V

– Working temperature -40℃~125℃

– Linearity deviation typically <±1.0°

– Provide standard 4-wire SPI interface (maximum clock 16MHz) to read 14-bit angle data inside the chip

– Incremental output ABZ supports any resolution from 1 to 1024 lines (each pair of magnetic poles)

– Incremental output UVW supports 1~16 arbitrary pairs of poles (each pair of magnetic poles)

– Provide 12-bit PWM output

Application:

industrial robot joints, AGV vehicles (automatic guided vehicles), etc.
