General Description
The TC649 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 fur-
nishes the required control voltage of 1.25V to 2.65V
(typical) for 0% to 100% PWM duty cycle. The TC649
automatically suspends fan operation when measured
temperature (V
IN
) is below a user programmed
minimum setting (V
AS
). An integrated Start-up Timer
ensures reliable motor start-up at turn-on, coming out
of shutdown mode, auto-shutdown mode or following a
transient fault.
In normal fan operation, a pulse train is present at
SENSE (Pin 5). The TC649 features Microchip
Technology’s proprietary FanSense
TM
technology for
increasing system reliability. A missing pulse detector
monitors this pin during fan operation. A stalled, open
or unconnected fan causes the TC649 to trigger its
Start-up Timer once. If the fault persists, the FAULT
output goes low, and the device is latched in its shut-
down mode. See Section 5.0, “Typical Applications”,
for more information and system design guidelines.
The TC649 is available in the 8-pin PDIP, SOIC and
MSOP packages and is available in the industrial and
extended commercial temperature ranges.
