The 2-wire serial interface accepts standard System Management Bus (SMBus) 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. Accuracy of speed measurement is ±4%. Applications include desktop computers, notebook computers, projectors, servers and networking equipment.\u003c\/p\u003e\n  \u003cul\u003e\n   \u003cli\u003eTwo thermal-diode inputs, up to 25KHz PWM output frequency\u003c\/li\u003e\n   \u003cli\u003eThree selectable SMBus addresses\u003c\/li\u003e\n   \u003cli\u003eLocal temperature sensor, 1°C remote temperature accuracy\u003c\/li\u003e\n   \u003cli\u003eTwo PWM outputs for fan drive (open drain, can be pulled up to +13.5V)\u003c\/li\u003e\n   \u003cli\u003eProgrammable fan-control characteristics, automatic fan spin-up ensures fan start\u003c\/li\u003e\n   \u003cli\u003eControlled rate-of-change ensures unobtrusive fan-speed adjustments\u003c\/li\u003e\n   \u003cli\u003e±3% fan-speed measurement accuracy\u003c\/li\u003e\n   \u003cli\u003eTemperature monitoring begins at POR for FailSafe system protection\u003c\/li\u003e\n   \u003cli\u003eActive-low OT and active-low THERM outputs for throttling or shutdown\u003c\/li\u003e\n   \u003cli\u003e0°C to +150°C measurement range, 16 QSOP package, -40°C to +125°C operating range\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003ch3\u003eWarnings\u003c\/h3\u003e\n  \u003cp\u003eMarket demand for this product has caused an extension in leadtimes.
