Designer’s Notes
The time constant gained by external components C2 and R2 is used to set the length of an ‘off’ operation time period after
phase switching. This means that the variable-speed operations can be performed by changing the ‘on’ operation time of each
phase through the duty control.
.
The sawtooth waveform signals are generated by the C2-R2 time constant. The voltage of this signal (Ct pin voltage) increases
from 1.3 V to 4.0 V (Vct) at each phase switching. That is, during this period, the driver becomes inactive (t
off
), in which
output circuit is turned off.
.
If V
CC
^
4.0 V, the driver IC remains active (t
on
) until the next phase switching. During this period, output circuit is turned on.
.
If the active drive time of each phase is assumed to ‘t
o
’, the following relation can be established:
