AS5055

Low Power 12-Bit Magnetic Rotary Encoder

1 General Description

The AS5055 is a single-chip magnetic rotary encoder IC with low

voltage and low power features.

2 Key Features

12-bit resolution

Standard SPI interface, 3 or 4 wire

It includes 4 integrated Hall elements, a high resolution ADC and a

smart power management controller.

3.0V to 3.6V core voltage, 1.8V to 3.6V peripheral supply

voltage

The angle position, alarm bits and magnetic field information are

transmitted over a standard 3-wire or 4-wire SPI interface to the host

processor.

Automatic wake-up over SPI interface

Interrupt output for conversion complete indication

Low power mode:

The AS5055 is available in a small QFN 16-pin 4x4x0.85 mm

package and specified over an operating temperature of -40ºC to

+85ºC.

- < 5mA (avg) @ 1ms readout interval

- < 500µA (avg) @ 10ms readout interval

- < 53µA (avg) @ 100ms readout interval

Small size 16-pin QFN (4x4x0.85 mm)

3 Applications

The device is ideal for Servo motor control, Input device for battery

operated portable devices, and Robotics.
