The charge current is programmable, so you can set the rate to match the battery capacity without changing the IC — a single BOM line serves multiple pack sizes by adjusting one resistor. Maximum supply voltage is 5.5 V, meaning a standard 5 V USB rail or a regulated 5 V adapter is the right input; a 12 V supply needs a pre-regulator. Surface-mount assembly with Tube packaging — the Tube is a standard anti-static shipping format for SOIC, suitable for pick-and-place feeders with tube-to-tape conversion.","metaTitle":"BQ2954SN Texas Instruments Li-Ion Battery Charger IC","metaDescription":"BQ2954SN from Texas Instruments: Li-Ion battery fast charger IC in 16-SOIC.
