Description
General part information
LM96163 Series
The LM96163 has remote and local temperature sensors with integrated fan control that includes TruTherm BJT transistor beta compensation technology for remote diode sensing. The LM96163 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 LM96163 has an offset register to correct for errors caused by different non-ideality factors of other thermal diodes.
The LM96163 also features an integrated, pulse-width-modulated (PWM), open-drain fan control output. Fan speed depends on a combination of the remote temperature reading, the lookup table and register settings. The 12-step Lookup Table (LUT) enables the user to program a non-linear fan speed vs. temperature transfer function often used to quiet acoustic fan noise. In addition a fully programmable ramping function has been added to allow smooth transitions between LUT setpoints.
