Overview
ADM1031 Intelligent Temperature Monitor and Dual PWM Fan Controller The ADM1031 is an ACPI-compliant, three-channel digital thermometer and under/overtemperature alarm for use in personal computers 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.
com 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 reprogramme...
