| AS5050 Low Power 10-Bit Magnetic Rotary Encoder 1 General Description The AS5050 is a single-chip magnetic rotary encoder IC with low voltage and low power features. It includes 4 integrated Hall elements, a high resolution ADC and a smart power management controller. 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. The AS5050 is available in a small QFN 16-pin 4x4x0.85 mm package and specified over an operating temperature of -40ºC to 85ºC. 2 Key Features resolution SPI interface, 3 or 4 wire to 3.6V core voltage, 1.8V to 3.6V peripheral supply voltage wake-up over SPI interface output for conversion complete indication power mode: - < 5mA avg 1ms readout interval - < 500µA avg 10ms readout interval - < 53µA avg 100ms readout interval 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.
