Sensorless Spindle Motor Controller

GENERAL DESCRIPTION The ML4411 provides complete commutation for delta or wye wound Brushless DC (BLDC) motors without the need for signals from Hall Effect Sensors. This IC senses the back EMF of the three motor windings (no neutral required) to determine the proper commutation phase angle usi

Sensorless Spindle Motor Controller

GENERAL DESCRIPTION\nThe ML4411 provides complete commutation for delta or wye wound Brushless DC (BLDC) motors without the need for signals from Hall Effect Sensors. This IC senses the back EMF of the three motor windings (no neutral required) to determine the proper commutation phase angle using P ■ Back-EMF commutation provides maximum torque for minimum “spin-up” time for spindle motors\n■ Accurate, jitter-free phase locked motor speed feedback output\n■ Linear or PWM motor current control\n■ Easy microcontroller interface for optimized start-up sequencing and speed control\n■ Power fail de;
