Datasheet - Detailed Descr i pti on
The PWM frequency can be programmed by the OTP bits PWM_frequency (1:0). Therefore, four different frequencies are possible.
Taking into consideration the AC characteristic of the PWM output including load, it is recommended to use the clamping function. The
recommended range is 0% to 4% and 96% to 100%.
7.4 Kick Down Function
The AS5163 provides a special compare function. This function is implemented using a programmable angle value with a programmable
hysteresis. It will be indicated over the open drain output pin KDOWN. If the actual angle is above the programmable value plus the hysteresis,
the output is switched to low. The output will remain at low level until the value KD is reached in the reverse direction.
