Overview
ADM1030
Intelligent Temperature Monitor and PWM Fan Controller
The ADM1030 is an ACPI-compliant two-channel digital thermometer and under/over temperature alarm, for use in computers and thermal management systems.
Optimized for the Pentium III, the higher 1C accuracy offered allows systems designers to safely reduce temperature guardbanding and increase system performance.
A Pulsewidth Modulated (PWM) Fan Control output controls the speed of a cooling fan by varying output duty cycle.
Duty cycle values between 33%–100% allow smooth control of the fan.
The speed of the fan can be monitored via a TACH input for a fan with a tach output.
The TACH input can be programmed as an analog input,...
