LM63 Datasheet (National Semiconductor) - Accurate Remote Diode Digital Temperature Sensor

LM63, Accurate Remote Diode Digital Temperature Sensor

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 commonly found on Computer Processors, Graphics Processor Units (GPU) and othe

LM63 Features

* an integrated, pulse-widthmodulated (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
