LM63
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 diodeconnected transistor, such as a 2N3904, or a thermal diode monly found on puter 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. For the latest information contact hardware.monitor.team@nsc.. The LM63 also features an integrated, pulse-widthmodulated (PWM), open-drain fan control output. Fan speed is a bination 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...
