AS5147P-HTSM

AS5147P-HTSM is a 14-bit on-axis magnetic rotary position sensor with a 12bit binary incremental pulse count and 28krpm high-speed capability. It is a high-resolution rotary position sensor for high-speed (up to 28krpm) 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 AS5147P and to program non-volatile settings without a dedicated programmer. The AS5147P 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.
