MT6835 21-Bit High Accuracy Magnetic Angle Encoder IC

PublishTime：2022-10-13

●MagnTek's rotary position sensor MT6835 is an IC based on advanced AMR technology. A rotating magnetic field in the x-y sensor plane delivers two sinusoidal output signals which indicating the angle (a)between the sensor and the magnetic field direction.
●The sensor is only sensitive to the magnetic field direction in x-y plane as the sensing element output is specially designed to be independent from the magnetic field strength.This allows the device to be less sensitive to magnet variations,stray magnetic fields,air gap changes and off-axis misalignment.
●Theincremental ABZ output mode is available in this sensor series,making the chip suitable to replace various optical encoders.The maximum resolution is 16,384 pulses or 65,536 steps per revolution
●A 4-Wire SPI interface allows a host microcontroller to read out the 21-bit absolute angle position data from MT6835.The absolute angle position is also provided as a 12-bit PWM output.
●Features and Benefits:
■Based on advanced AMR Technology with 0~360°Full Range Angle Sensing
■21-bit Core Resolution with Maximum Rotation Speed Up to 120,000 RPM
■Output Propagation Delay <10 us
■User Auto-Calibration and Distortion Compensation with Target INL<±0.07°
■-40~125°C Operating Temperature Range
■Independent Output Interface: ABZ, UVW，PWM and SPI
■Incremental ABZ Resolution 1~16,384 Pulses per Revolution User Programmable
■UVW Output Resolution 1~16 Pole-Pairs per Revolution User Programmable
■3.3~5.0V Programmable EEPROM
