It monitors each cell for over-voltage, under-voltage, and over-temperature conditions, triggering a fault output when any threshold is exceeded. Housed in a 24-TSSOP package (0.173\", 4.40 mm width) for surface-mount assembly, the part operates across a -40°C to 85°C ambient temperature range — covering the full industrial thermal envelope for battery management systems in portable tools, e-bikes, energy storage, and backup power units. ## Active production — no end-of-life watch needed No pin-compatible second source or official successor is documented in the TI portfolio for this exact function and cell-count range. The BQ7721602PWR is a single-source line item — the BOM should carry a risk flag if volume continuity is critical, though the active status means supply is stable for the foreseeable future. ## Package and procurement posture Supplied in Tape & Reel (TR) or Cut Tape (CT) format, the 24-TSSOP body has a 0.65 mm pin pitch typical for this footprint family. The surface-mount package suits automated pick-and-place assembly; no special handling beyond standard MSL precautions is required.","metaTitle":"TI BQ7721602PWR Battery Protection IC, 3~16 Cells, 24-TSSOP","metaDescription":"Active Texas Instruments BQ7721602PWR battery protection IC for 3-16 Li-ion cells.
