Pin Function
Thermistor 1 (Input): Analog input of approximately 30% to 70% of V
produces active duty cycle of 0% to 100% at driver output (OUT). Connect to
external thermistor network (or other temperature sensor). Pull low for shutdown.
PWM Timing Capacitor (External Component): Positive terminal for the PWM
triangle-wave generator timing capacitor. The recommended C
30Hz PWM operation.
Sleep Threshold (Input): The voltage on this pin is compared to VT1 and VT2.
When V
rises above V
mode function.
Ground.
Thermistor 2 (Input): Analog input of approximately 30% to 70% of V
produces active duty cycle of 0% to 100% at driver output (OUT). Connect to
motherboard fan control signal or second temperature sensor.
Overtemperature Fault (Output): Open-collector output (active low).Indicates
overtemperature fault condition (V
Driver Output: Asymmetrical-drive active-high complimentary PWM output.
Typically connect to base of external NPN motor control transistor.
Power Supply (Input): IC supply input; may be independent of fan power supply.
