ML4435 - Sensorless BLDC Motor Controller
The ML4435 provides all the circuitry for sensorless speed control of 3 phase Brushless DC Motors.
Controller functions include start-up circuitry, Back EMF commutation control, Pulse Width Modulation (PWM) speed control, pulse-by-pulse current limiting, motor coasting, and undervoltage protection.
ML4435 Features
* Proprietary back-EMF sensing commutation technique for motor communication 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-sta
