Lead-acid charge controller in 16-SOIC
The Texas Instruments BQ24450DW is a lead-acid battery charge controller IC in the 16-SOIC package. It manages the charge cycle for sealed and flooded lead-acid chemistries, handling a maximum supply voltage of 40 V. The surface-mount SOIC-16 footprint (0.295" body width, 7.50 mm) is standard for medium-power analog ICs.
40 V supply ceiling and thermal envelope
The 40 V maximum supply voltage means the BQ24450DW can regulate charge from a 24 V AC adapter or a solar panel string that reaches 36 V open-circuit — the internal series-pass element and control logic survive the full rail without an external pre-regulator. At the 70°C upper limit the die temperature stays within the silicon rating as long as the SOIC-16's thermal pad (if present) sees a copper plane on the PCB.
