Contact factory for other temperature selections.
T
L
and T
H
can be selected in 5°C increments. T
H
must
be chosen at least 10°C higher than T
L
. T
L
can range
anywhere from 25°C to 35°C.
As an example, suppose you wanted the fan to
run at
40% speed at 25°C
or less and go to
full speed at
45°C.
You would order the part number TC652AEVUA.
As another example, suppose you wanted the fan to
turn on at 30°C
and go to
full speed at 45°C.
You
would order the part number TC653BEVUA.

TYPICAL APPLICATIONS
4.1
Reducing Switching Noise
For fans consuming more than 300mA, a slowdown
capacitor (C
SLOW
) is recommended for reducing
switching PWM induced noise (see Figure 4-1). The
value of this capacitor should be 4.7
μ
F to 47
μ
F,
depending on the fan current consumption.
See Application Note AN771 “Suppressing Acoustic
Noise in PWM Fan Speed Control Systems” for more
information.
