AEAT-6600-T16：10 to16-Bit Programmable Angular Magnetic Encoder IC

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.

AEAT-6600主要特性：

5 V or 3.3 V operation

3-wire or 2-wire SSI interface mode for absolute output

Incremental ABI or UVW, and PWM output modes

User-programmable zero position, direction & index pulse width

Easy magnet alignment with magnetic field strength output and alignment mode



ower-down mode to reduce current consumption

TSSOP-16 IC package

RoHS compliant

AEAT-6600指標：

Absolute 10-bits to 16-bits resolution

Incremental output resolutions 8 to 1024 CPR

-40℃ to 125℃ operating temperature range

AEAT-6600應用：

3-phase commutation for brushless DC motor

Resolver and potentiometer replacement

Industrial automation and robotics
