DESCRIPTION
The UCC3626 motor controller device bines 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...
