It monitors one cell and triggers protection for over-current, over-voltage, under-voltage, and short-circuit faults — the four events that can send a Li-Ion pack into thermal runaway or permanent capacity loss. The 6-WSON package (1.5x1.5 mm) keeps the footprint small enough for a battery-management PCB that fits inside the pack housing. ## Package and board-fit — 6-WFDFN / 6-WSON The BQ29701DSET ships in a 6-WFDFN package (also designated 6-WSON) with a 1.5x1.5 mm body. The supplier device package is 6-WSON (1.5x1.5). Surface-mount only — no through-hole option. The small pad pitch means the PCB land pattern must match the TI recommended footprint to avoid solder bridging on the thermal pad. For a production run, the reel is the economical choice; for prototyping or a small BOM fill, the cut tape avoids buying a full reel quantity. ## Lifecycle and compliance — active, ROHS3, no PCN watch needed yet For a BOM that needs a single-cell protector with a known supply chain, this part is a safe pick. No second-source or cross-reference is listed by TI, so the BOM line is single-sourced to this order code.","metaTitle":"BQ29701DSET Battery Protection IC, 1-Cell Li-Ion, 6-WSON","metaDescription":"Texas Instruments BQ29701DSET battery protection IC for 1-cell Li-Ion/Polymer packs.
