BQ25185 Charger Topology
GRM21BZ71A226ME15L / C907991 como candidato con PROCUREMENT_STATUS = PENDING_APPROVAL.MCP41HV51-503E/ST) labels TSSOP-14 pin 8 as NC and pin 9 as DGND. Microchip datasheet DS20005207B, Table 3-1, specifies pin 8 = DGND and pin 9 = NC.DGND_SERVICE. This is electrically acceptable because Microchip requires DGND at ground and recommends connecting NC to either DGND or VL to reduce noise coupling. Flux reports No-connect pin connected: U10:NC; this is a justified library-metadata ERC finding, not an unintended electrical connection.U10:NC connected because of the pin 8/9 metadata defect.DGND_SERVICE for power-save mode.AIRTAG_CELL_POS is driven by V_CELL_PLACEHOLDER, an explicit schematic-only 1S source marker excluded from PCB, BOM and pick-and-place. It is not a real battery selection.Current full ERC disposition
