General 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.

Key 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.
