Description
General part information
LM96063 Series
The LM96063 is remote diode temperature sensors with integrated fan control that includes remote diode sensing. The LM96063 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 LM96063 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 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.
The LM96063 is targeted mainly for a transistor MMBT3904 used as thermal diodes or thermal diodes found in many FPGAs, ASICs, and processors on SOI processes. The LM96163 is identical to the LM96063 except the TruTherm BJT Beta compensation is enabled at power up that is targeted for thermal diodes found on popular processors using bulk non SOI processes.
