AS5047U-HTSM

AS5047U-HTSM is a 14bit on-axis magnetic rotary position sensor with up to 14-bit binary incremental pulse count. It is a high-resolution rotary position sensor for fast absolute angle measurement over a full 360-degree range. This new position sensor is equipped with a revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency at higher rotational speed. For increased signal quality at lower rotational speed, the dynamic filter system (DFS™) reduces transition noise. The robust design of the device suppresses the influence of any homogenous external stray magnetic field. The AS5047U supports BLDC motor commutation for the most challenging industrial applications such as factory automation, building automation, robotics, PMSM (permanent magnet synchronous motor), stepper motor closed loop, optical encoder replacement.

• Easy to use saving costs on DSP, DAEC™ dynamic angle error compensation, DFS™ dynamic filter system
• Higher durability and lower system costs (no shield needed), magnetic stray field immunity
• Versatile choice of the interface, independent output interfaces: SPI, ABI, UVW, PWM
• Positive supply voltage range from 4.5 to 5.5V (5.0V operation mode)
• Regulated voltage range from 3.2 to 3.6V (voltage at VDD3V3 pin if VDD ≠ VDD3V3)
• Maximum supply current is 16mA
• Maximum speed is 28000rpm, dynamic angle error is 0.02° max
• Measurement range (default) from -28000 to 28000rpm
• Velocity total error is ±5% (based on actual rotation speed)
• 14-TSSOP package, ambient operating temperature range from -40 to 150°C
