ADM1034  
Thermal Monitor and Fan  
Speed (RPM) Controller  
The ADM1034 is a dualchannel remoteand localtemperature  
sensor and fan controller. The remote channels monitor the  
temperature of two remote thermal diodes, which may be discrete  
2N3904/6s or may be located on a microprocessor die. The device also  
monitors its own ambient temperature.  
http://onsemi.com  
The ADM1034 can monitor and control the speed of two cooling  
fans. The user can program a target fan speed, or else use the lookup  
table to input a temperaturetofan speed profile. The lookup table  
can be configured to run the fans at discrete speeds (discrete mode) or  
to ramp the fan speed with temperature (linear mode).  
The ADM1034 communicates over a 2wire SMBus 2.0 interface.  
An 8level LOCATION input allows the user to choose between  
SMBus 1.1 and SMBus 2.0. An ALERT output indicates error  
conditions. The THERM I/O signals overtemperature as an output and  
times THERM assertions as an input. Pin 8 can be configured as a  
reference for the THERM (PROCHOT) input.
