The MAX1501ZETE+: It accepts a maximum supply voltage of 6.25 V and integrates over-voltage fault protection, making it suited for portable and handheld equipment where a single input rail powers the charge cycle.
The MAX1501ZETE+ supports multi-chemistry battery types — it is not limited to a single chemistry, so it can charge Li-Ion, Li-Poly, NiMH, or NiCd cells depending on the charge algorithm implemented by the host controller.
The MAX1501ZETE+ supports charging 1 to 3 series-connected cells. The pinout is defined in the datasheet for the 16-TQFN (5x5) package; the number of cells is typically set via external resistor dividers on the CELLS pin.
For a different cell count or charge current, consider other members of the MAX1501 family, but verify pinout and package compatibility against the BOM.
