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. The supplier device package is also 16-TSSOP, so the land pattern is identical across the distributor's stock. No exposed pad to worry about, but the narrow body means the usual 0.3 mm trace escape under the part is tight — a via-in-pad or dogbone fanout on the inner pins helps keep the layout clean.
Lifecycle and supply — active, no obsolescence flag
For a BOM line that needs a multi-chemistry charger in a 16-TSSOP, this part is a stable selection without a forced migration path.
