It monitors the cell for over-current, over-voltage, under-voltage, and short-circuit conditions, pulling the discharge FET gate low to isolate the load when any threshold is exceeded. Operating from -40°C to 85°C, it fits portable consumer gear, power tools, and medical devices that see ambient extremes but not under-hood automotive heat. The 6-WSON (1.5x1.5) package keeps the footprint small enough for a battery protection PCB that fits inside the pack wrapper. ## Sourcing and second-source fit For a BOM that already carries the BQ29732DSET, the BQ29733DSER drops into the same 6-WSON land pattern and shares the same pin function — no board spin needed.","metaTitle":"Texas Instruments BQ29733DSER Battery Protection IC","metaDescription":"Texas Instruments BQ29733DSER battery protection IC for 1-cell Li-Ion/Polymer packs.
