General Description

The AS5050A is a single-chip magnetic 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.
