Analog Devices ADM1034 Thermal Monitor and Fan Speed Controller Datasheet
The ADM1034 is a thermal monitor and fan speed (RPM) controller designed for desktop and notebook PCs, embedded systems, telecommunications equipment, and LCD projectors. It functions as a dual-channel remote- and local-temperature sensor, monitoring two remote thermal diodes and its own ambient temperature with +1°C accuracy.
The device controls the speed of two cooling fans using either a programmable target speed or a look-up table configured for discrete speeds or linear ramping. Communication occurs over a 2-wire SMBus 2.0 interface, which supports address input via LOCATION and includes features like an ALERT output for error conditions and fail-safe overtemperature comparators.
