Fan Speed Controllers

Analog Devices fan speed controllers provide all the functionality necessary for a power management system to regulate the speed of a fan via a 2-wire SMBus/I²C interface. Fan speeds are regulated per a system’s required temperature profile and results in lower fan power consumption, longer battery run time, and lower acoustical generated noise vs. systems that use simple on-off fan control.
