Description
1
RC
One-shot multivibrator pulse width setting. Connect a resistor between this pin and VREG, and a capacitor between this
pin and ground.
6V regulator output. Connect a capacitor between this pin and ground for stabilization.
2
VREG
3
VCC
C
Power supply. Connect a capacitor between this pin and ground for stabilization.
4
Duty pulse signal smoothing and soft start time setting. Connect a capacitor between this pin and VREG.
5
CTL
Duty pulse signal input. The speed is controlled by the duty of this pulse signal.
6
FGIN
FG pulse input
7
LIM
Minimum speed setting. Normally, the 6V regulator level is resistor divided to set this pin's input level.
8
GND
Ground pin
9
EI
One-shot multivibrator output and integrating amplifier input. A capacitor must be connected between this pin and EO for
this integration.
Integrating amplifier output.
