Function
Equivalent circuit
5
VCC1
2.0V to 6.0V
Power supply connection.
6
VS
0V to VCC2
Motor drive and speed control blocks power
supply.
The voltage applied to this pin must be strictly
lower than VCC2.
7
VCC2
2.0V to 6.0V
Power supply connection for the pre-drive circuit
and the motor back EMF detection comparator
circuit.
8
FG
FG output.
These are open collector output.
8
VCC1
9
FC
Frequency characteristics determination closed
loop oscillation of the current control system can
be stopped by connecting a capacitor between
this pin and GND.
