Source Current : 1mA Max. at control voltage 0V
Sink Current : 1mA Max. at control voltage 3.8V
Control Terminal Voltage : 3.8V 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.
