Avago’s AEAT-6600-T16 is the industry’s highest resolution Hall magnetic encoder, including Hall element, analog front end and digital signal processing. It has a resolution of 10-16 bits and can accurately measure the angle of 360-degree rotation. The working voltage of the device is 5V or 3.3V, the absolute value output of the 3-wire or 2-wire SSI interface mode, the incremental ABI or UVW and the PWM output mode, the user-programmable zero position, pointing and marking pulse width, mainly used in industrial automation And robots, instead of resolvers and potentiometers, three-phase commutation of brushless DC motors, etc. This article introduces the main features and indicators of AEAT-6600-T16, OTP editable mode circuit diagram, alignment mode circuit diagram, PCB level application circuit diagram and Main features of HEDS-8937 programmer, etc.
The Avago AEAT-6600 angular magnetic encoder IC is a contact less magnetic rotary encoder for accurate angular measurement over a full turn of 360 degrees.
It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device.
To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC.
The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.005° = 65 536 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.
An internal voltage regulator allows the AEAT-6600 to operate at either 3.3 V or 5 V supplies.
