Text: TEMPERATURE SENSORS and THERMAL MANAGEMENT Dec 10, 2002 Speed Control For Isolated -48V Fans A circuit is shown that allows a MAX6650 fan speed regulator IC to control a high-voltage fan on the other side of an isolation barrier. Chips are available to monitor and control ventilation fans. Less common are fan controllers for
