PWM Duty Cycle （ % ） =
PWM Frequency 25 （ kHz ） =
Source Current （ Isource ） : 1mA Max. at control voltage 0V
Sink Current （ Isink ） : 1mA Max. at control voltage 5.25V
Control Terminal Voltage : 5.25V Max. (Open Circuit)
When the control lead wire is no connecting,
the speed is the same speed as at 100% of PWM cycle.
This fan speed should be controlled by PWM input signal
of either TTL input or open collector, drain input.
