(3) FG signal output waveform
From the Hall input signal, a pulse signal (FG signal) is output proportional to the motor speed of rotation. This timing
is shown in Fig.9 below.
(4) Other
For the PS pins, the circuits turn on at 3.5 V or greater, and enter the power save mode at 1.5 V or less. For the REV pin,
it enters the reverse mode at 4.0 V or greater, and enters the normal mode at 1.5 V or less.
