LM63
www.ti.com SNAS190E – SEPTEMBER 2002 – REVISED MAY 2013 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 Вµm Pentium 4 and Mobile Pentium 4
Processor-M thermal diode. The LM63 has an offset
register to correct for errors caused by different nonideality factors of other thermal diodes. 1 23 Accurately Senses Diode-Connected 2N3904
