Product Overview

AS5147-HTSM is a 14-bit on-axis magnetic rotary position sensor with an 11-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. The robust design of the device suppresses the influence of any homogenous external stray magnetic field. A standard 4-wire SPI serial interface allows a host microcontroller to read 14-bit absolute angle position data from the AS5147 and to program non-volatile settings without a dedicated programmer. The AS5147 has been designed to support BLDC motor commutation for the most challenging automotive applications (AEC-Q100 grade 0 automotive qualified) such as electric power steering (EPS), transmission (gearbox, actuator), pump, brake (actuator) and starter and alternator.
  • Easy to use – saving costs on DSP, DAEC™ Dynamic angle error compensation
  • Good resolution for motor and position control, 14bit core resolution
  • Versatile choice of the interface, independent output interfaces: SPI, ABI, UVW, PWM
  • No programmer needed (via SPI command), zero position, configuration programmable
  • Supports safety challenging applications, self-diagnostics
  • Lower system costs (no shielding), immune to external stray field
  • Positive supply voltage range from 4.5 to 5.5V (5.0V operation mode)
  • Supply current is 15mA maximum
  • Sampling rate range from 202 to 247ns (refresh rate at SPI)
  • TSSOP-14 package, temperature range from -45 to 150°C
