LSI-LS7262 | Anaheim Automation, Inc.

The LS7260/LS7262 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-LS7262 and LSI-LS7262-S has a minimum purchase requirement of 10 pieces, regardless of stock. LSI-LS7262-TS are Limited to Stock on Hand. LSI-LS7262-S is NRND (Not Recommended for New Designs).
