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
modulation (PWM). A thermistor (or other voltage output temperature sensor)
connected to the VIN input furnishes 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 (VIN) is below a user
programmed minimum setting (VAS). 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 FanSenseTM 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 shutdown 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.
