The MAX1873REEE+ is a multi-chemistry battery charger IC designed to charge 2-series cell packs to 8.4 V. The charge current is constant and programmable, with a maximum of 4 A — this sets the charge-time floor for a given pack capacity.
The supplier device package is also listed as 16-QSOP — same footprint, same pinout. The 0.025" pitch demands a standard SSOP land pattern; no fine-pitch reflow profile required.
Yes — the IC supports multi-chemistry charging for 2 cells, with a battery pack voltage of 8.4 V, which matches the 2S Li-Po float voltage.
