Therefore:
t

= 6.6μs
t

= 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
