(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.
