Figure 11. Output Current Regulation Waveforms
Figure 12 shows the magnitude of the Off Time t

values. It can be approximately
calculated from the equations:

where R

and C

are the external component values and t

t
DT
= 1μs (typical value)
Therefore:
t
OFF(MIN)
= 6.6μs
t
OFF(MAX)
= 6ms
These values allow a sufficient range of t
OFF
to implement the drive circuit for most motors.
The capacitor value chosen for C
OFF
also affects the Rise Time t
RCRISE
of the voltage at the pin RCOFF. The
Rise Time t
RCRISE
will only be an issue if the capacitor is not completely charged before the next time the
monostable is triggered. Therefore, the on time t
ON
, which depends by motors and supply parameters, has to
be bigger than t
RCRISE
for allowing a good current regulation by the PWM stage. Furthermore, the on time t
ON
can not be smaller than the minimum on time t
ON(MIN)
.
