PWM Regulation
In order to force a given current (determined by <Irun>
or <Ihold> and the current position of the rotor) through
the motor coil while ensuring high energy transfer
efficiency, a regulation based on PWM principle is used. The
regulation loop performs a comparison of the sensed output
current to an internal reference, and features a digital
regulation generating the PWM signal that drives the output
switches. The zoom over one micro ? step in the Figure 18
above shows how the PWM circuit performs this regulation.
To reduce the current ripple, a higher PWM frequency is
selectable. The RAM register PWMfreq is used for this.

1 45,6 kHz
PWM Jitter
To lower the power spectrum for the fundamental and
higher harmonics of the PWM frequency, jitter can be added
to the PWM clock. The RAM register <PWMJEn> is used
for this.
