DESCRIPTION:

The LS7260 / LS7262 are 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 the motor position sensors, to provide electronic commutation of the motor windings.

FEATURES:

● Direct drive of P-Channel and N-Channel FETs (LS7260)

● Direct drive of PNP and NPN transistors (LS7262)

● Six outputs drive power switching bridge directly

● Open or closed loop motor speed control

● +5V to +28V operation (VSS – VDD)

● Externally selectable input to output code for 60°,

● 120°, 240°, or 300° electrical sensor spacing

● Three or four phase operation

● Analog speed control

● Direction control

● Output enable control

● Positive static braking

● Over-current sensing

● LS7260, LS7262 (DIP); LS7260-S, LS7262-S (SOIC);

● LS7260-TS, LS7262-TS (TSSOP) – See Connection Diagram.
