Selector Guide
The MAX8903_ is available in several options designat-
ed by the first letter following the root part number. The
basic architecture and functionality of the
MAX8903A–MAX8903E/MAX8903G/MAX8903Y are the
same. Their differences lie in certain electrical and
operational parameters. Table 6 outlines these differ-
ences.

Typical values. See the Electrical Characteristics table for min/max values.
Note that this also changes the timing for the prequal and fast-charge timers.
See the Power Enable on Battery Detection section for details.
The MAX8903H is a newer version of the MAX8903C that is a recommended for new designs.
