MIC502  
Fan Management IC  
General Description  
Features  
The MIC502 is a thermal and fan management IC that  
supports the features for NLX/ATX power supplies and  
other control applications.  
• Temperature-proportional fan speed control  
• Low-cost, efficient PWM fan drive  
• 4.5V to 13.2V IC supply range  
• Controls any voltage fan  
• Overtemperature detection with fault output  
• Integrated fan startup timer  
• Automatic user-specified sleep mode  
• Supports low-cost NTC/PTC thermistors  
• 8-pin DIP and SOIC packages  
Fan speed is determined by an external temperature  
sensor, typically  
a
thermistor-resistor divider, and  
(optionally) a second signal, such as the NLX “FanC”  
signal. The MIC502 produces a low-frequency pulse-width  
modulated output for driving an external motor drive  
transistor. Low-frequency PWM speed control allows  
operation of standard brushless DC fans at low duty-cycle  
for reduced acoustic noise and permits the use of a very  
small power transistor. The PWM time base is determined  
by an external capacitor.  
Applications  
• NLX and ATX power supplies  
• Personal computers  
• File servers  
An open-collector overtemperature fault output is asserted  
if the primary control input is driven above the normal  
control range.  
• Telecom and networking hardware  
• Printers, copiers, and office equipment  
• Instrumentation  
• Uninterruptible power supplies  
• Power amplifiers  
The MIC502 features a low-power sleep mode with a user-  
determined threshold. Sleep mode completely turns off the  
fan and occurs when the system is asleep or off (both  
control inputs very low). A complete shutdown or reset can  
also be initiated by external circuitry as desired.  
The MIC502 is available as 8-pin plastic DIP and SOIC  
packages in the –40°C to +85°C industrial temperature  
range.
