General Description
The TC648 is a switch mode, fan speed controller for
use with brushless DC fans. Temperature proportional
speed control is accomplished using pulse width mod-
ulation (PWM). A thermistor (or other voltage output
temperature sensor) connected to the V
IN
input
furnishes the required control voltage of 1.25V to 2.65V
(typical) for 0% to 100% PWM duty cycle. The TC648
can be configured to operate in either auto-shutdown or
minimum speed mode. In auto-shutdown mode, fan
operation is automatically suspended when measured
temperature (V
IN
) is lower than a user programmed
minimum setting (V
AS
). The fan is automatically
restarted, and proportional speed control restored,
when V
IN
exceeds V
AS
(plus hysteresis). Operation in
minimum speed mode is similar to auto-shutdown
mode, with the exception that the fan is operated at a
user programmed minimum setting when the mea-
sured temperature is low. An integrated Start-up Timer
ensures reliable motor start-up at turn-on, and when
coming out of shutdown or auto-shutdown mode.
The over-temperature fault output (OTF) is asserted
when the PWM reaches 100% duty cycle, indicating a
possible thermal runaway situation.
The TC648 is available in the 8-pin plastic DIP, SOIC
and MSOP packages and is available in the industrial
and extended commercial temperature ranges.
