App note from Maxim Integrated about their MAX6650 and MAX6651 fan controllers chip. Temperature-based fan control is a necessity in a growing number of systems, both to reduce system noise and to improve fan reliability. When fan control is augmented by fan-speed monitoring, a speed-control loop can be implemented that is independent of manufacturing variances […]
