ML4411 Features

* s s s s s s s Back-EMF commutation provides maximum torque for minimum “spin-up” time for spindle motors Accurate, jitter-free phase locked motor speed feedback output Linear or PWM motor current control Easy microcontroller interface for optimized start-up sequencing and speed control Power fail de

ML4411 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 using Phase Lock Loop techni.
