LS7362 BRUSHLESS DC MOTOR COMMUTATOR/CONTROLLER

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 moto.

LS7362 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.
