    Since "BM5291 Ver 13" appears to be a specific internal project code, board revision, or proprietary hardware design (likely a power management IC evaluation board, an industrial controller, or a consumer electronics prototype), I have structured this write-up as a comprehensive Engineering Verification Report. Reset Circuit: The RC reset circuit and push-button

    This document is designed to serve as the formal record of the schematic verification process. You can adapt the specific technical details (component names, voltage rails, etc.) to match your actual hardware.

    The schematic verification was conducted using a multi-stage approach:
