Product Description
Product Overview
The Magntek MT6701 is a next-generation magnetic angle sensor chip based on differential Hall effect principles. It offers 0-360 absolute angle position detection with a wide operating voltage range of 3.3V to 5.0V. The chip features multiple independent output interfaces including I2C, SSI, ABZ, UVW, analog voltage, PWM, and Z-axis press detection. It supports high rotational speeds up to 55,000 RPM with a system delay of less than 5 s for angle output. The MT6701 is designed for applications requiring precise angle measurement, such as closed-loop stepper and BLDC motor control, robotic joint control, and non-contact rotary and push-button interfaces. Its robust design includes excellent resistance to stray magnetic fields and is RoHS compliant.
