UCC2626 - Brushless DC Motor Controller

Download the UCC2626 datasheet PDF (UCC3626 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for brushless dc motor controller.

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.

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.
