What the DS2712Z+ is and where it fits
The Maxim Integrated DS2712Z+ is a multi-chemistry battery charger controller designed to charge one or two cells in series. It supports NiMH, NiCd, and lithium-ion chemistries, making it a flexible fit for portable equipment, handheld instruments, and backup-battery applications where the cell type may vary across product variants or supply chains. Housed in a 16-pin SOIC package (3.90 mm width) with surface-mount termination, it occupies minimal board area and suits automated assembly. The operating temperature range of -20°C to 70°C covers indoor commercial and light industrial environments, but not automotive under-hood or extended outdoor exposure. Maximum supply voltage is 5.5 V.
Multi-chemistry support — what it means for the BOM
The DS2712Z+ handles NiMH, NiCd, and Li-ion cells without a hardware change. That means a single charger design can serve products that switch chemistries between production runs — for example, a medical monitor that uses NiMH in one revision and Li-ion in the next. No separate charger IC per chemistry, no board spin. The 1-2 cell count range covers single-cell Li-ion and two-cell NiMH packs.
Lifecycle and sourcing posture
The DS2712Z+ carries an Active product status per the manufacturer's latest lifecycle record. There is no NRND flag, no last-time-buy notice, and no announced end-of-life. For procurement planning, this part is safe for new designs and ongoing production without LTB risk. ROHS3 compliant, no lead or restricted-substance concerns for EU or global markets.
