For a 1-cell pack, the over-voltage threshold typically trips around 4.3 V to prevent cell damage during charging, while the under-voltage lockout cuts the load at roughly 2.5 V to avoid deep discharge. The over-current detection range is set by external resistors — the IC itself provides the comparator and timing, so the actual trip point is a design choice, not a fixed number. A pack that sees a cold warehouse floor at -20°C or a hot dashboard at 70°C stays within the rated envelope. ## Active production and compliance The ROHS3 status means it meets the latest EU restriction limits, including the four phthalates added in 2015. ## Package options for prototype vs volume The IC is offered in both Tape & Reel (TR) for automated pick-and-place and Cut Tape (CT) for small-quantity prototyping. The 6-WFDFN package (also called 6-WSON with a 1.5x1.5 mm body) has a 0.5 mm pitch — fine enough that a standard soldering iron works, but a hot-air rework station makes placement easier. The exposed pad on the bottom must be soldered to a PCB thermal land for proper heat sinking; the datasheet recommends a 2.0x2.0 mm pad with four vias to the ground plane.","metaTitle":"BQ29707DSER Battery Protection IC, 1-Cell Li-Ion, 6-WSON","metaDescription":"Texas Instruments BQ29707DSER battery protection IC for 1-cell Li-Ion/Polymer packs.
