The Texas Instruments UC2906DW is a lead-acid battery charger controller in a 16-SOIC surface-mount package. It handles the charge profile for sealed or flooded lead-acid cells — the chemistry is hard-coded for the voltage and current taper that lead-acid needs. The part operates from a 40 V max supply and includes programmable current limiting, so you set the charge current with an external sense resistor.
