The ams OSRAM AS5147U magnetic rotary position sensor represents a significant leap in automotive electrification, designed to enhance efficiency and safety in high-speed electric motors for critical vehicle functions like power steering, braking, and active damper control. This intelligent sensor supports the industry's drive towards greener, smarter vehicles.
A unique design integrates advanced technologies for unparalleled performance. The AS5147U features DFS™ (Dynamic Filter System) for accurate, low-noise position measurements, coupled with DAEC™ (Dynamic Angle Error Correction) for virtually zero latency and ultra-accurate real-time angle measurement at rotation speeds up to 28,000rpm. This patented combination, exclusive to ams OSRAM, maximizes motor torque and efficiency. The sensor also benefits from an internal DSP core, performing measurement processing directly on the chip.
A special feature is its inherent immunity to stray magnetic fields, thanks to a patented differential sensing architecture. This eliminates the need for costly shielding materials, reducing system complexity and overall cost. For enhanced safety, the AS5147U embeds a comprehensive suite of self-diagnostic features and Cyclic Redundancy Check (CRC) protection for external communications, supporting strict ISO 26262 functional safety standards. This highly integrated solution provides versatile output formats including 14-bit ABI, UVW and digital PWM, SPI and is qualified to AEC-Q100 Grade 0, dual redundant chip version ASIL-D capable, all in a compact 14-lead TSSOP package.
