LS7262 Datasheet (LSI Computer Systems) - BRUSHLESS DC MOTOR COMMUTATOR/CONTROLLER

LS7262, BRUSHLESS DC MOTOR COMMUTATOR/CONTROLLER

The LS7260/LS7262 are monolithic, MOS integrated circuits designed to generate the signals necessary to control a three phase or four phase brushless DC motor.

They are the basic building blocks of a brushless DC motor controller.

The circuits respond to changes at the SENSE inputs, originating at
