Description

This reference design provides a simple way to spin and control a 5V, 3-phase, BLDC fan motor with minimum development time and overhead. It utilizes the DRV10866, a sensorless BLDC motor driver, for the power stage and a TLC555 timer to provide a variable duty cycle PWM signal for speed control. The DRV10866 uses a 150 degree sensorless BEMF control scheme that takes away the need for external sensors on the motor.

Features
  • Low Voltage, 150 Degree BEMF Sensorless Motor Control
  • Speed Control Through Onboard Potentiometer
  • Compact Board Size (Can Fit Onto Fan Itself)
  • Can Be Powered From Micro-USB Cable, No Power Supply Required
  • Low Development Overhead, Design is Orderable and Tested
  • No Firmware Required, No MCU Required
