The part supports 1 to 3 series cells, and the battery pack voltage is listed as 8.4V, which corresponds to a 2-cell Li-Po full-charge voltage. For 3 cells (12.6V full charge), the charger can be configured within the 16V max supply — the cell count is set by external resistor programming."},{"question":"Is the BQ24125RHLRG4 a direct replacement for BQ24125RHLR?","answer":"The BQ24125RHLR and BQ24125RHLRG4 share the same base product number BQ24125 and the same 20-VQFN package. The G4 suffix indicates lead-free (RoHS) compliance and Tape & Reel packaging — electrically they are identical. The RHLR variant is the non-G4 version; confirm your BOM's RoHS requirement before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24125RHLRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24125RHLRG4 when reusing this data.
