ams OSRAM AG AS5147U rotary position sensor

AS5147U is a high-resolution magnetic rotary position sensor for fast absolute angle measurement over a full 360-degree range. The robust design suppresses the influence of any homogenous external stray magnetic field. The 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.

Key features

• Magnetic Stray Field Immunity
• DAEC™ Dynamic Angle Error Compensation DFS™ Dynamic Filter System
• Independent Output Interfaces: SPI, ABI, UVW, PWM
• Developed According to ISO26262

Additional features:

• AEC-Q100 Grade 0 qualified
• Additional Benefits:
  • Easy to use - saving costs on DSP
  • Higher durability and lower system costs (no shield needed)
  • Enabler for safety-critical applications
  • Suitable for automotive applications
  • Versatile choice of the interface

Applications

• BLDC Motor Communication
• Electric Power Steering (EPS)
• Transmission (Gearbox, Actuator)
• Brake (Actuator)
• Starter/Alternator
