Abstract :
A low-cost, high-efficiency, compact architecture of a PWM (pulse-width-modulation) drive fan controller is designed for use in an embedded multicomputer system with an integrated hierarchical thermal management scheme. This pure digital design yields lower cost and higher conventional linear drive fan providing the functionality and advantages of PWM drive fan controllers. The implementation and system integration of this circuit is also described in this paper
