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 nonALERT
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.
