LAN9215I - Highly Efficient Single-Chip 10/100 Ethernet Controller with HP Auto-MDIX and Industrial Temperature Support

General Description
 The MAX6639 monitors its own temperature and one external diode-connected transistor or the temperatures of two external diode-connected transistors, typically available in CPUs, FPGAs, or GPUs.
The 2-wire serial interface accepts standard System Management Bus (SMBusTM) write byte, read byte, send byte, and receive byte commands to read the temperature data and program the alarm thresholds.
Temperature data can be read at any time over the SMBus, and three programmable alarm outputs can be used to generate interrupts, throttle signals, or overtemperature shutdown signals.
The temperature data is also used by the internal dual-PWM fan-speed controller to adjust the speed of up to two cooling fans, thereby minimizing noise when the system is running cool, but providing maximum cooling when power dissipation increases.
Speed control is accomplished by tachometer feedback from the fan, so that the speed of the fan is controlled, not just the PWM duty cycle.
Accuracy of speed measurement is ±4%.
The MAX6639 is available in 16-pin QSOP and 16-pin thin QFN 5mm x 5mm packages.
It operates from 3.0V to 3.6V and consumes just 500μA of supply current.

Features
* Two Thermal-Diode Inputs
* Up to 25kHz PWM Output Frequency
* Three Selectable SMBus Addresses
* Local Temperature Sensor
* 1°C Remote Temperature Accuracy
* Two PWM Outputs for Fan Drive (Open Drain; Can be Pulled Up to +13.5V)
* Programmable Fan-Control Characteristics
* Automatic Fan Spin-Up Ensures Fan Start
* Controlled Rate-of-Change Ensures Unobtrusive Fan-Speed Adjustments
* ±3% Fan-Speed Measurement Accuracy
* Temperature Monitoring Begins at POR for Fail- Safe System Protection
* OT and THERM Outputs for Throttling or Shutdown
* Measures Temperatures Up to +150°C
* MAX6639F is Optimized for n = 1.021 for Penryn Compatability

Applications
* Desktop Computers
* Notebook Computers
* Projectors
* Servers

MAX6639 - 2-Channel Temperature Monitor with Dual, Automatic, PWM Fan-Speed Controller

General Description
The MAX6662 is a 12-bit + sign temperature sensor combined with a programmable overtemperature alarm and a 3-wire (SPI™-compatible) serial interface in a single package. It converts its die temperature into digital values using an internal analog-to-digital converter
(ADC). The temperature data is stored in a temperature register as a 13-bit word, which allows 0.0625°C resolution.
The temperature data is readable at any time through the serial interface. The operating temperature range is -55°C to +150°C.
The MAX6662 provides two programmable watchdog interrupt outputs. ALERT is used for lower temperature warning functions, while OT is used for higher temperature- critical functions, such as power-supply shutdown.
The MAX6662 features a shutdown mode that saves power by disabling everything except the serial interface.
The temperature sensor is available in an 8-pin SO package.

Features
* 12-Bit + Sign, 0.0625°C Resolution
