Figure 8. Data Transmission with Pulse Width Modulated (PWM) Output
The PWM signal will be generated from the actual stored angle information. The zero-angle corrected value is buffered
and fixed until the next PWM-sequence is started. To ease the filtering of the PWM signal, a minimum pulse width is
implemented in the protocol.
Analog Output
This configuration is similar to the PWM connection (only three lines including supply are required). With the addition of
a lowpass filter at the PWM output, this configuration produces an analog voltage that is proportional to the angle. This
filter can be either passive (as shown in
analog output can be achieved. If the AS5134 angular data is invalid, the PWM output will remain at low state and thus
the analog output will be 0V. Pins that are not shown may be left open.
