General Description

: 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 the motor position sensors, to provide electronic commutation of the motor windings.

Key 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 Spee.
