ML4435 Datasheet | Fairchild Semiconductor

Sensorless BLDC Motor Controller .fairchildsemi. Features - Proprietary back-EMF sensing mutation technique for motor munication without hall effect sensors - PWM pulse-by-pulse current limiting to protect motor and FET drivers - Stand-alone operation; motor starts and stops with power applied to the IC- - Soft-start function limits start-up current - PWM speed control for efficiency and minimum FET sizing - Onboard under voltage lock out and power fail detect - Tach output senses mutation of the motor Description The ML4435 provides all the circuitry for sensorless speed control of 3 phase Brushless DC Motors. Controller functions include start-up circuitry, Back...
