LSI-LS7260 | Anaheim Automation, Inc.

The LS7260 are MOS integrated circuits designed to generate the signals necessary to control a three 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 the motor position sensors, to provide electronic commutation of the motor windings. Overcurrent circuitry is provided to protect the windings, associated drivers and power supply.

Note: LSI-LS7260-S and LSI-LS7260C has a minimum purchase requirement of 10 pieces, regardless of stock. LSI-LS7260 and LSI-LS7260-TS are Limited to Stock on Hand.
