Source Current : 1mA Max. at control voltage 0V
Sink Current : 1mA Max. at control voltage 5.25V
Control Terminal Voltage : 5.25V Max. (Open Circuit)
When the control lead wire is open,
the fan speed is the same as the one at a PWM duty cycle of 100% .
Either TTL input, open collector or open drain can be used for PWM control input signal.
Fans do not rotate when PWM duty cycle is 0ˋ.
