VIH
PWM duty cycle (%) =
VIL=0 V to 0.4 V
T1
×100
T
PWM frequency 25 (kHz) = 1
T
Source current (Isource) : 1 mA max. at control voltage 0 V
Sink current (Isink) : 1 mA max. at control voltage 5.25 V
Control terminal voltage: 5.25 V 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.
