LS7260-TS Datasheet PDF - LSI Computer Systems

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.
