  • Speed Error in PWM Fan Control Systems
    Brushless DC fan (BDC) speed can be varied using pulse-width modulation (PWM). The typical PWM control scheme inserts a power switch in series with the fan, as shown in Figure 1. In such applications, an increase in the active duty cycle causes a corresponding increase in fan speed (i.e., fan speed...

  • Linear Voltage Fan Speed Control Using Microchip's TC64X Family
    Pulse Width Modulation (PWM) fan speed control methodology pulse-width modulates a fan's full-rated power supply voltage at a low frequency, typically 30 Hz. A typical PWM circuit, consisting of a transistor in series with a fan, can be small and inexpensive because it is either fully...

  • Interfacing Microchip's Fan Speed Controllers to a SPITM
    , significantly extending fan life. In addition to increased fan life, fan speed is controlled by PWM control circuitry that is more efficient than conventional linear techniques. The ICs provide other features such as fan current limiting, minimum speed control, auto shutdown, and speed, fault...
