Additional preview pages of the ML4435 datasheet.

The ML4435 provides all the circuitry for sensorless speed control of 3 phase Brushless DC Motors.

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-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 commuta.
