LM96163

Remote Diode Digital Temperature Sensor with Integrated

Fan Control and TruTherm^®BJT Transistor Beta

Compensation Technology

LUT transition fine resolution smoothing function

General Description

Tachometer input for measuring fan RPM

The LM96163 has remote and local temperature sensors with

Smart-Tach modes for measuring RPM of fans with pulse-

width-modulated power as shown in typical application

ALERT output for processor event notification

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 er-

rors caused by different non-ideality factors of other thermal

■

TCRIT output for critical temperature system shutdown

Offset register can adjust for a variety of thermal diodes

10-bit plus sign and 11-bit unsigned formats, with 1/8°C

resolution

Extended resolution to 1/32°C when digital filter enabled

Resolves remote diode temperatures up to 255.875°C

The LM96163 also features an integrated, pulse-width-mod-

ulated (PWM), open-drain fan control output. Fan speed de-

pends 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.
