DESCRIPTION:

The LS7362 is a monolithic, ion implanted MOS circuit designed to generate the signals necessary to control a three phase or four phase brushless DC motor. It is the basic building block of a brushless DC motor controller. The circuit responds to changes at the SENSE inputs, originating at the motor position sensors, to provide electronic commutation of the motor windings.

FEATURES:

• Speed Control by Pulse Width Modulation (PWM)

of low-side drivers only.

• Open or closed loop motor speed control.

• +5 to +28 Volt 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.

• Forward/Reverse control.

• Output Enable control.

• Positive Static Braking.

• Overcurrent Sensing.

• Six outputs drive switching bridge directly.

• LS7362 (DIP); LS7362-S (SOIC);

LS7362-TS (TSSOP) - See Connection Diagram
