Temperature Selection Guide
(Minimum Fan Speed/Full Speed)
There are two temperature thresholds that determine
the characteristics of the device. The minimum fan
speed temperature (T L ) and the full fan speed temper-
ature (T H ). Depending on the TC65X device selected,
when the temperature is below the T L trip point, the
PWM output will perform a different operation. For the
TC650, the PWM will be driven at the minimum PWM
frequency, while the TC651 will shut down the PWM
(PWM = L).
T L and T H can be selected in 5°C increments. T L can
and T L temperature thresholds. The following exam-
ples are given to assist in understanding the device-
ordering nomenclature.
Example 1: 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 TC650AEVUA.
Example 2: 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
TC651BEVUA.
range from 25°C to 35°C. T H can range from 35°C to
55°C and must be 10°C (or more) than the specified T L .
The five temperature regions defined by the six
thresholds are defined in the TC650/TC651 by means of

factory trimming. Once a T L and T H are set, the T 1 – T 4
thresholds are automatically equally spaced between T L
and T H . Table 4-1 shows these 5 regions and what the
corresponding PWM duty cycle is.

The temperature regions defined by the
six temperature thresholds are pre-
defined in the TC650/TC651 by means of
factory trimming. Once a T L and T H are
programmed, the T 1 – T 4 thresholds are
automatically equally spaced between T L
