AMS OSRAM GROUP AS5055A-BQFM Magnetic Position Sensor, 12 Bit, QFN-16, 3 to 3.6 VDC, SMD, AS5055A Series

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
