output stage flyback diode voltage.
Off Time One Shot
The off time one shot guarantees that a minimum
off time occur in the output of the spindle PWM
waveforms. This prevents subharmonic cycling,
and prevents partial transition in the output wave-
form. Additionally, it provides a fixed time delay
which allows acurate synchronizing of the PWM
waveform with the commutation input (SP_CLK).
Finally, it prevents tolerance buildups in the cir-
cuitry because the PWM_DC circuitry can be de-
signed to allow higher than full scale voltage with-
out fear for causing audible subharmonics.
Output Comparator
This comparator produces the PWM chop duty
cycle for use within the spindle drivers, now cor-
rected for power supply variation.
On delay Comparator
The on delay comparator provides a warning sig-
nal for the back EMF detection circuit brackets
the worst part of the turnon transient that occurs
on the back emf detection winding.
