AS5047P-ATSM

AS5047P-ATSM is a 14bit on-axis magnetic rotary position sensor with 12-bit decimal and binary incremental pulse count for 28krpm high speed capability. It is a high-resolution rotary position sensor for high speed (up to 28krpm) angle measurement over a full 360° range. This new position sensor is equipped with revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency and offers a robust design that suppresses of the influence of any homogenous external stray magnetic field. The AS5047P is ideally suited to support BLDC motor commutation for the most challenging industrial applications such as factory automation, building automation, robotics, PMSM (permanent magnet synchronous motor) and stepper motors closed loop regulation, as well as optical encoder replacement application.

• High speed application, up to 28krpm
• Easy to use saving costs on DSP, DAEC™ Dynamic angle error compensation
• Good resolution for motor and position control, 14bit core resolution
• Simple optical encoder replacement
• No programmer needed (via SPI command), zero position, configuration programmable
• Versatile choice of the interface, independent output interfaces: SPI, ABI, UVW, PWM
• Lower system costs (no shielding), immune to external stray field
• Positive supply voltage range from 4.5 to 5.5V (5.0V operation mode)
• Sampling rate range from 202 to 247ns (refresh rate at SPI), maximum speed is 28000RPM
• 14-pin TSSOP package, ambient temperature range from -40 to 125°C (in the 5V power supply mode only)
