UCC2626 - Brushless DC Motor Controller

This page provides the datasheet information for the UCC2626, a member of the UCC3626 Brushless DC Motor Controller family.

Datasheet Summary

Description

The UCC3626 motor controller device combines many of the functions required to design a high-performance, two- or four-quadrant, threephase, brushless dc motor controller into one package.

Rotor position inputs are decoded to provide six outputs that control an external power stage.

Features

  • D Two-Quadrant and Four-Quadrant Operation D Integrated Absolute Value Current Amplifier D Pulse-by-Pulse and Average Current Sensing D Accurate, Variable Duty-Cycle Tachometer Output D Trimmed Precision Reference D Precision Oscillator D Direction Output.

UCC2626, UCC3626 SLUS318B – APRIL 1999 – REVISED JANUARY 2002 BRUSHLESS DC MOTOR CONTROLLER FEATURES D Two-Quadrant and Four-Quadrant Operation D Integrated Absolute Value Current Amplifier D Pulse-by-Pulse and Average Current Sensing D Accurate, Variable Duty-Cycle Tachometer Output D Trimmed Precision Reference D Precision Oscillator D Direction Output DESCRIPTION The UCC3626 motor controller device combines many of the functions required to design a high-performance, two- or four-quadrant, threephase, brushless dc motor controller into one package. Rotor position inputs are decoded to provide six outputs that control an external power stage. A precision triangle oscillator and latched comparator provide PWM motor control in either voltage- or current-mode configurations.
