    Hello,

    1. The TPS2549 integrates a CS functionality where the TPS2546 integrates the ILIM_SEL. The TPS2549 also offers Divider 3 charging mode, while the TPS2546 offers only Divider 1 and 2.

    2. Yes, the TPS2549 supports 2.4A charging spec

    3. Yes. If you look within both of the datasheets under section 6.5 Electric Characteristics, you will see Supply Current which outlines the different levels of current drawn of the TPS2549/TPS2546 depending on the mode it is programmed for
