3藲C Accurate Remote Diode Digital Temperature
Sensor with Integrated Fan Control
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鈥檚. The LM63 remote
temperature sensor鈥檚 accuracy is factory trimmed for the
series resistance and 1.0021 non-ideality of the Intel

廬
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-
odes.

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.
