ML4426 Datasheet (Micro Linear) - Bi-directional Sensorless BLDC Motor Controller

ML4426, Bi-directional Sensorless BLDC Motor Controller

The ML4426 PWM motor controller provides all of the functions necessary for starting and controlling the speed of delta or wye wound Brushless DC (BLDC) motors without Hall Effect sensors.

Back EMF voltage is sensed from the motor windings to determine the proper commutation phase sequence using a P
