Abstract: PURPOSE: A counter electromotive force detection circuit of a sensorless BLDC(Brushless DC) motor and a method thereof are provided to improve the efficiency of the motor by detecting an accurate counter electromotive force even when the motor operates in a low RPM. CONSTITUTION: A three phase full bridge circuit drives a three phase sensorless BLDC motor. A first LPF(Low Pass Filter) unit filters the signal of an angular in the output of the motor. A second LPF unit changes a reference value toward the counter electromotive force level of the angular in the output of the motor. A comparator unit outputs the signal of the counter electromotive force to a pulse wave. The comparator unit compares the voltage of the first LPF unit and the second LPF unit.
