AS5047P − General Description

Applications

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 in as well optical encoder replacement.
