Lead-acid charge controller in a 16-pin DIP
The Texas Instruments UC2906N is a dedicated lead-acid battery charger controller in a 16-DIP through-hole package. It manages the charge profile for lead-acid chemistries — the most common flooded, gel, and AGM cells — with programmable current limiting via an external sense resistor. Rated for a maximum supply of 40 V, the part handles nominal 12 V and 24 V battery banks with headroom for the charging voltage above the float level. The -40°C to 70°C ambient range covers most indoor and outdoor industrial enclosures; the die's junction temperature stays within the plastic DIP's thermal limits at moderate charge currents.
Package, mounting, and compliance
The 16-PDIP footprint is standard — 0.100" pitch, 0.300" row spacing — and mates with a DIP socket or solders directly into a plated-through-hole board. The supplier device package is 16-PDIP. Texas Instruments lists the UC2906N as ROHS3 compliant, meaning it meets the Restriction of Hazardous Substances directive with no exempted applications of lead, mercury, cadmium, or the other restricted substances.
Because the part is active, new designs can proceed without a migration plan. The 16-DIP package is a mature, widely stocked form factor; independent distributors carry it alongside the authorized channel.
