External RC Network (pin 14)
The external RC network provides the higher of
the two possible chopping frequencies. The dis-
charge time of the capacitor represents the mini-
mum t
(ON)
availablein closed loop. In open loop it
is possibleto select asmaller t
(ON)
, (see Fig.20).
The t
(ON)
min defines the min current the IC can
supply to the motor, as well as the protection
”window”. This window is necessary to mask the
spike generated at the beginning of each chop-
ping period (see Fig.21a).
Figure20:
Oscillator waveformand timing.
The window must be large enough to mask this
spike, without penalizing excessively the min cur-
rent control. The capacitor C mainly defines the
value of the window. The mathematical formulas
to calculate theapproximatevalues are:
