P82CF201 Datasheet (NXP) - Low power / low price dual fan manager

P82CF201, Low power / low price dual fan manager

The P82CF201 is a 20-pin single-chip dual digital fan controller designed for use with brushless DC fan motors.

A thermistor (or temperature resistive sensor) connected to the RthermC input provides the required resistance of 10K to 1.75 KΩ for 30% to 98% PWM duty cycle.

With temperature less than 2

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 P82CF201 also features fan fault sensing for enhancing system protection and reliability. It detects the presence of a fan, when the running fan fails or jams using th
