ADT7481  
Dual Channel Temperature  
Sensor and Overtemperature  
Alarm  
The ADT7481 is a 3−channel digital thermometer and under/ over  
temperature alarm, intended for use in PCs and thermal management  
systems. It can measure its own ambient temperature or the  
temperature of two remote thermal diodes. These thermal diodes can  
be located in a CPU or GPU, or they can be discrete diode connected  
transistors. The ambient temperature, or the temperature of the remote  
thermal diode, can be accurately measured to 1°C. The temperature  
measurement range defaults to 0°C to +127°C, compatible with  
ADM1032, but can be switched to a wider measurement range from  
−64°C to +191°C.

The ADT7481 communicates over a 2−wire serial interface  
compatible with System Management Bus (SMBus) standards. The  
SMBus address of the ADT7481 is 0x4C. An ADT7481−1 with an  
SMBus address of 0x4B is also available.  
An ALERT output signals when the on−chip or remote temperature  
is outside the programmed limits. The THERM output is a comparator  
output that allows, for example, on/off control of a cooling fan. The  
ALERT output can be reconfigured as a second THERM output if  
required.
