AMG-XB404
Fully Integrated Single Motor Controller for Electrical Motors
If D5V drops below the brown-out voltage VBO the power-on reset unit will trigger a reset of the FLL
unit which will in turn reset the digital core of the AMG-XB404. The AMG-XB404 will resume
operation with the power-on reset cycle described above as soon as D5V rises above VPOR. Power-
on reset and brown-out reset scenarios are detailed in figure 40.
