AS5050A
Low Power 10-Bit Magnetic Position Sensor
General Description
The AS5050A is a single-chip on-axis magnetic rotary position sensor with low voltage and low power features.
It includes an integrated Hall element array, a high resolution ADC and a smart power management controller.
The angle position, alarm bits and magnetic field information are transmitted over a 3-wire or 4-wire SPI interface to the microcontroller.
The AS5050A is available in a compact QFN 16-pin 4x4x0.85 mm package and specified over an operating temperature of -40ºC to 85ºC.
Ordering Information and Content Guide appear at end of datasheet.
