LM63 ±1°C/±3°C Accurate Remote Diode Digital Temperature Sensor with Integrated Fan  
Control  
Check for Samples: LM63

FEATURES  
DESCRIPTION  
The LM63 is a remote diode temperature sensor with  
integrated 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 Processor 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 diodes.

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.
