1 / 46 page  LM96063 www.ti.com SNIS149B – NOVEMBER 2011 – REVISED MARCH 2013 LM96063 Remote Diode Digital Temperature Sensor with Integrated Fan Control Check for Samples: LM96063 1 FEATURES APPLICATIONS 2 • Accurately Senses Remote Diode-Connected • Communications Infrastructure FPGA, ASIC or MMBT3904 Transistors or Thermal Diodes On- Processor Thermal Management Board Processors, FPGAs or ASICs • Electronic Test and Office Equipment • Accurately Senses Its Own Local Die • Industrial Controls Temperature • Offset Register can Adjust for a Variety of DESCRIPTION Thermal Diodes The LM96063 is remote diode temperature sensors with integrated fan control that includes remote diode • Resolves Remote Temperatures up to sensing. The LM96063 accurately measures: (1) its 255.875°C own temperature and (2) the temperature of a diode- • 10-bit Plus Sign and 11-bit Unsigned Data connected transistor, such as a 2N3904, or a thermal Formats, with 1/8°C Resolution diode commonly found on Computer Processors, • Digital Filter of Remote Data Lowers Noise and Graphics Processor Units (GPU) and other ASIC's. Improves Resolution to 1/32°C The LM96063 also features an integrated, pulse- • Integrated PWM Fan Speed Control Output width-modulated (PWM), open-drain fan control Supports High Resolution at 22.5kHz output. Fan speed is a combination of the remote temperature reading, the lookup table and register Frequency for 4-Pin Fans settings. The 12-step Lookup Table (LUT) enables • Acoustic Fan Noise Reduction with User- the user to program a non-linear fan speed vs. Programmable 12-Step Lookup Table temperature transfer function often used to quiet • LUT Transition Fine Resolution Smoothing acoustic fan noise. In addition a fully programmable Function ramping function has been added to allow smooth transitions between LUT setpoints. • Tachometer Input for Measuring Fan RPM with Smart-Tach Modes for Measuring RPM of Fans The LM96063 is targeted mainly for a transistor when Pulse-Width-Modulating an Actual Power MMBT3904 used as thermal diodes or thermal diodes found in many FPGAs, ASICs, and processors on • ALERT Output for Error Event Notification SOI processes. The LM96163 is identical to the • TCRIT Output for Critical Temperature System LM96063 except the TruTherm BJT Beta Shutdown compensation is enabled at power up that is targeted • SMBus 2.0 Compatible Interface, Supports for thermal diodes found on popular processors using TIMEOUT bulk non SOI processes. • WSON Packages Table 1.
