APPLICATIONS OF THE TA7712P/PG, TA7712F/FG
The TA7712P/PG and TA7712F/FG are provided with a stop function, which enables them to stop the motor having
a large inertia like a video disk player in a short time, so that disks can be changed quickly.
To eliminate the need of the frequency generator (FG), which was conventionally required for generating the
rotation signal, signals from the position sensor input are ORed and its synthesized signal is sent out from the
FGOUT pin (pin 11/13).
That is, since the FGOUT signal is a mixture of three position sensor outputs (Ha, Hb and Hc), its frequency is six
times that of each position sensor signal. This enables the TA7712P/PG and TA7712F/FG to achieve sufficient
control characteristics even with the F-V (frequency to voltage) convertor using a monostable multivibrator (MMV).
The difference between them and the TA7713P/PG is that the stop function is automated in the TA7713P/PG, while
it is operated by the external signal in the TA7712P/PG.
The following sections describe the applications of the TA7713P/PG.
(1) Functional Description on the FGOUT (pin 11/13) and TFG (pin 12/14) pins
Q1 and Q2 in Figure 1 comprise a monostable multivibrator. The position sensor input signals, Ha, Hb and Hc,
are combined together and applied to the base of Q2 after squaring waveform with a flip-flop, FF.
The output pulse width of the MMV consisting of Q1 and Q2 is determined by R2 and C2, which are connected
to TFG (pin 12/14).The square wave having the pulse width that is determined by C2 and R2 is generated from
FGOUT (pin 11/13). The frequency of this square wave, which is proportional to that of the rotation signal, is
six times the frequency of each position sensor signal. (Six pulses per electrical revolution)
The F-V conversion is performed by connecting the FGOUT output to a low-pass fileter and integrating the
output signal.
