LM63  
1˚C/ 3˚C Accurate Remote Diode Digital Temperature  
Sensor with Integrated Fan Control  
n 10 bit plus sign remote diode temperature data format,  
with 0.125˚C resolution  
n SMBus 2.0 compatible interface, supports TIMEOUT  
n LM86-compatible pinout  
n LM86-compatible register set  
n 8-pin SOIC package  
General Description  
The LM63 is a remote diode temperature sensor with inte-  
grated fan control. The LM63 accurately measures: (1) its  
own temperature and (2) the temperature of a diode-  
connected transistor, such as a 2N3904, or a thermal diode  
commonly found on Computer Processors, Graphics Pro-  
cessor Units (GPU) and other ASIC’s. The LM63 remote  
temperature sensor’s accuracy is factory trimmed for the  
series resistance and 1.0021 non-ideality of the Intel® 0.13  
µm Pentium® 4 and Mobile Pentium 4 Processor-M thermal  
diode. The LM63 has an offset register to correct for errors  
caused by different non-ideality factors of other thermal di-

The LM63 also features an integrated, pulse-width-  
modulated (PWM), open-drain fan control output. Fan speed  
is a combination of the remote temperature reading, the  
lookup table and the register settings. The 8-step Lookup  
Table enables the user to program a non-linear fan speed vs.  
temperature transfer function often used to quiet acoustic  
fan noise.
