Multi-chemistry charger for 1-2 series cells
The Maxim Integrated DS2712E+ is a multi-chemistry battery charger IC designed to charge one or two series cells. It handles NiMH, NiCd, and other chemistries without needing a separate charge-algorithm controller, making it a straightforward fit for portable equipment, handheld instruments, and backup-power boards where the BOM needs a single-chip charge manager. The 5.5 V supply maximum means it runs cleanly from a 5 V rail or a USB VBUS with margin; the -20°C to 70°C operating range covers indoor and most outdoor sheltered environments, though it is not rated for the -40°C extended industrial band.
Package and footprint — 16-TSSOP surface-mount
The DS2712E+ comes in a 16-TSSOP package (4.40 mm width) for surface-mount assembly. The 0.65 mm pitch is standard for this body size, and the tube shipping form suits low-to-medium volume builds without a reel fee.
