That 2.5 A ceiling is the practical limit for a 1S cell in a 24-VQFN (4x4) package — the exposed pad pulls heat into the board copper, so the actual charge rate depends on your PCB thermal design. The I²C interface lets you set the charge current, termination threshold, and safety timers on the fly — useful for systems that charge different battery packs or need to adjust the profile during a temperature sweep. ## Supply range and fault protection Maximum supply voltage is 17 V, which covers most USB-C and 5 V wall adapters with headroom for transients. The integrated fault protection — overcurrent, overtemperature, and overvoltage — means you don't need an external supervisor for basic safety; the chip shuts itself down before the cell sees a bad rail. The battery pack voltage is fixed at 4.2 V, so this part is strictly for 1S (single-cell) Li-Ion or Li-Poly packs. It will not charge a 2-cell stack — the 4.2 V regulation point is hardwired, not programmable via I²C.

The suffix difference (LRGET vs RGET) typically indicates tape-and-reel vs tube or different reel quantity — the die and pinout are identical. Confirm with the TI datasheet for the exact reel quantity difference, but for a board swap they are interchangeable."},{"question":"Does the BQ24195LRGET support I²C communication for charge control?","answer":"Yes — the I²C interface is the primary control bus. You can program the charge current, termination current, safety timer, and other parameters over I²C. There is no standalone pin-strap mode; the chip requires an I²C master to configure it after power-up."},{"question":"Can the BQ24195LRGET charge a 2-cell battery pack?","answer":"No. The battery pack voltage is fixed at 4.2 V and the number of cells is listed as 1. This part is designed exclusively for single-cell Li-Ion or Li-Polymer packs. For a 2-cell application, look at the BQ24170 or BQ24133 family from TI."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24195LRGET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24195LRGET when reusing this data.
