The 2A maximum charge current sets the charge-time floor for a given cell capacity. The current is constant and programmable, so you set the rate with an external resistor. If your design needs faster charging than 2A, this part is not the fit; if 2A is enough, the integrated protection and programmable timer keep the BOM lean.
For a BOM freeze, this part presents no near-term obsolescence risk.
Yes, it supports 1 to 3 cells and multi-chemistry packs including Li-Ion and Li-Polymer.
