ADM1029  
Dual PWM Fan Controller  
and Temperature Monitor for  
High Availability Systems  
The ADM1029 is a versatile fan controller and monitor for use in  
personal computers, servers, telecommunications equipment, or any  
high-availability system where reliable control and monitoring of  
multiple cooling fans is required. Each ADM1029 can control the  
speed of one or two fans and can measure the speed of fans that have a  
tachometer output. The ADM1029 can also measure the temperature  
of one or two external sensing diodes or an internal temperature  
sensor, allowing fan speed to be adjusted to keep system temperature  
within acceptable limits. The ADM1029 has FAULT inputs for use  
with fans that can signal failure conditions, and inputs to detect  
whether or not fans are connected.  
The ADM1029 communicates with the host processor over an  
System Management (SMBus) serial bus. It supports eight different  
serial bus addresses, so that up to eight devices can be connected to a  
common bus, controlling up to sixteen fans. This makes software  
support and hardware design scalable.  
The ADM1029 has an interrupt output (INT) that allows it to signal  
fault conditions to the host processor. It also has a separate, cascadable  
fault output (CFAULT) that allows the ADM1029 to signal a fault  
condition to other ADM1029s.  
The ADM1029 has a number of useful features including an  
automatic fan speed control option implemented in hardware with no  
software requirement, automatic use of backup fans in the event of fan  
failure, and supports hot-swapping of failed fans.
