Brushless DC Motor Application: Brushless Fan Control

Need a highly integrated fan controller with a customizable speed/temperature profile?Take a look at TECOTE LF series products.

• Built-in 5V regulator and on-chip comparator to save system cost
• Rotor position is determined by a Hall effect sensor connected to the on-chip comparator
• Enhanced Capture Compare PWM (ECCP) module uses feedback information to drive the motor by steering the PWM signal to the appropriate motor phase
• Temperature sensor inputs can be used to create a unique fan speed profile
• Application can provide digital status information to a host device
