ADM1031 Datasheet (ON Semiconductor) - Intelligent Temperature Monitor and Dual PWM Fan Controller

ADM1031, Intelligent Temperature Monitor and Dual PWM Fan Controller

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
