Product Overview

AS5055A-BQFM is a low-power 12bit magnetic position sensor. It 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. This sensor is optimized for a broad range of demanding applications including servo motor control, battery operated systems, and robotics.
  • Precise and reliable absolute angle measurement, 12bit absolute angle position indication
  • Very low power consumption, 3μA current consumption in low power mode
  • Synchronization between microcontroller and sensor, interrupt pin displays availability of new data
  • Ideal for small and compact designs
  • Industry-standard interface
  • Contactless absolute angle position measurement
  • Sensor for battery operated devices
  • Lower material cost (no magnetic shielding needed)
  • Readout rate is 500μs max (time between READ ANGLE command and INTERRUPT)
  • QFN-16 4x4 package, operating temperature range from -40 to 85°C
