AS5601 − Register Description

Figure 26:

Pushbutton Detection Function

The AS5601 continuously measures the magnetic field

intensity. The programmable threshold (PUSHTHR) is applied to

a long time average of the magnetic field. A crossing of the

current magnetic field and the threshold within a specified time

(tpu_slope) drives the PUSH output high.

Slow changes of the magnetic field, due for example to

temperature variations, magnet drift mechanical tolerances,

etc. do not generate any pushbutton detection events. The

push detection threshold follows the drifts over the time as

shown in Figure 27.
