Charging and data circuit schematic for the Samsung SM-A23, a 2.78 MB PDF. It covers the USB port path, the charger IC, overvoltage protection, data lines and the battery connection. This sheet is the first stop for not charging, slow charging, no PC connection or a short on VBUS, letting you trace current flow from the connector through protection to the charger. Check the board version and component markings against the drawing before replacing a charger IC or protection part.
