... K ) and THRESHOLD is set to LOW, the fan will be off. When temperature rises above 25 C (NTC thermistor at 10K or less), the PWM turns the fan on. The P82CF201 features a Turn-on Delay for a second fan when both fans have to turn-on. This reduces the in-rush current and suppresses acoustic noise. ...

... The RC charging time of the reference resistor and thermistor are measured. The thermistor value is calculated by comparing the RC time of the Reference resistor and RC time of the thermistor ((RthermistorCTime*Rreference)/RreferenceCTime) thermistor 3 Product data P82CF201 V SENSE2 FAULT V SENSE1 FAULT RESET FAN1DRIVE ...
