AS5047P − Detailed Description

UVW Commutation Interface

The AS5047P can emulate the UVW signals generated by the

three discrete Hall switches commonly used in BLDC motors.

The UVWPP field in the SETTINGS register selects the number

of pole pairs of the motor (from 1 to 7 pole pairs). The UVW

signals are generated with 14-bit resolution.

During the start-up time, after power ON of the chip, the UVW

signals are low.

Figure 33:

UVW Signals

The Figure 33 shows the UVW signal flow if the magnet rotates

in clockwise direction, placing the magnet on the top of the

AS5047P and looking at the magnet from the top (DIR=0). With

the bit DIR, it is possible to invert the rotation direction.
