EVALUATION KIT AVAILABLE  
MAX31790  
6-Channel PWM-Output Fan RPM Controller  
General Description  
Features  
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 I C  
interface. The outputs drive “4-wire” fans directly, or can  
be used to modulate the fan’s power terminals using an  
external pass transistor.  
S Controls Up to Six Independent Fans with PWM Drive  
S Up to 12 Tachometer Inputs

S Controlled Duty Cycle Rate-of-Change for Best  
Acoustics  
2
S I C Bus Interface with Timeout and Watchdog  
Tachometer inputs monitor fan tachometer logic outputs  
for precise (Q1%) monitoring and control of fan RPM as  
well as detection of fan failure. Six pins are dedicated  
tachometer inputs. Any of the six PWM outputs can also  
be configured to serve as tachometer inputs.  
S 3.0V to 5.5V Supply Voltage Range  
S 1.5mA (typ) Operating Supply Current  
Applications  
The PWM_START inputs select the PWM output status  
at startup to ensure appropriate fan drive when power is  
first applied.  
Servers  
Networking  
Telecom  
To ensure low acoustic impact of fan control, all changes  
in PWM duty cycle take place at a controlled, program-  
mable rate.  
Ordering Information appears at end of data sheet.  
The MAX31790’s 3.0V to 5.5V supply voltage range and  
I C-compatible interface make it ideal for fan control in

a wide range of cooling applications. The MAX31790 is  
available in a 28-pin TQFN package and operates over  
the -40NC to +125NC temperature range.
