Fan Speed Controller and Fan Fault Detector Family
The and are TC642, TC646, TC647, TC648 TC649
fan speed controller products that support external
temperature input.
The and TC642B, TC646B, TC647B, TC648B TC649B
are fan speed controller products that support external
temperature input and incorporate a fan auto-restart
function.
The and are fan speed TC654, TC655, TC664 TC665
controller products that support external temperature
input and two-wire serial communication.
The , and devices are TC64X, TC64XB, TC65X TC66X
pulse width modulation (PWM) fan speed controllers
for DC brushless fans. These devices adjust the speed
of the fan according to the temperature level, thereby
reducing acoustic noise, minimizing power consumption,
and extending fan life. A thermistor or other temperature
dependent voltage output device can be used to supply
the VIN voltage, which sets the required duty cycle
drive signal on VOUT. The TC654/TC655 and TC664/
TC665 products allow the user to control fan speed
and communicate data via a Standard Management
Bus (SMBus) interface. These devices also enable the
user to read fan RPM data and implement predictive fan
failure detection. The entire family features a pulse width
modulation (PWM) frequency of 30 Hz (CF = 1 µF) and an
operating current of less than 0.5 mA.
This family is fully specified from 3.0V to 5.5V over a
-40°C to +85°C temperature range. Numerous features
address a broad spectrum of applications, such as,
shutdown mode for further power savings, FanSense™
technology for fan fault detection, auto-shutdown for
automatic fan shut-off, minimum fan speed for constant
cooling and over temperature alert for overheating
detection. The TC64X and TC64XB devices are available
in 8-pin
PDIP
, MSOP and SOIC packages. The TC65X and
TC66X are available in a 10-pin MSOP package.
These products are ideal for every application utilizing
DC fans, especially where acoustic noise and fan
reliability are critical. Suitable applications include
computers, projectors, servers, datacom equipment,
telecom equipment, power supplies, set-top boxes, fan
racks and test equipment.

Temperature proportional fan speed control
FanSense™ technology protects against fan and
system failure
