MAX31790 Datasheet - Maxim Integrated

MAX31790 6-Channel PWM-Output Fan RPM Controller

The MAX31790 controls the speeds of up to six fans using six independent PWM outputs. The desired fan speeds (or PWM duty cycles) are written through the I2C interface. The outputs drive “4-wire” fans directly, or can be used to modulate the fan’s power terminals using an external pass transistor. T.

MAX31790 Features

* Provides Precise Fan Control and Monitoring for Large Fan Count Applications

* Controls Up to Six Independent Fans with PWM Drive

* Up to 12 Tachometer Inputs

* Controlled Duty Cycle Rate-of-Change for Best Acoustics

* Improves System Reliability
