LS7362 - BRUSHLESS DC MOTOR COMMUTATOR/CONTROLLER

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.

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.
