ADM1031 Datasheet | onsemi

Intelligent Temperature Monitor and Dual PWM Fan Controller The ADM1031 is an ACPI-pliant, three-channel digital thermometer and under/overtemperature alarm for use in personal puters and thermal management systems. Optimized for the PentiumIII, the part offers a 1C higher accuracy, which allows system designers to safely reduce temperature guard-banding and http://onsemi. increase system performance. Two PWM fan control outputs control the speed of two cooling fans by varying output duty cycle. Duty cycle values between 33% and 100% allow smooth control of the fans. The speed of each fan can be QSOP- 16 CASE 492 monitored via TACH inputs, which can be...
