It delivers a constant charge current up to 900 mA to a 4.2 V battery pack, with over-voltage fault protection built in. The control interface combines I²C and USB, allowing the system host to manage charging parameters and monitor status over a standard serial bus. ## Package and temperature grade for portable integration Housed in a 25-bump WFBGA / WLBGA package (2.31 x 2.31 mm body, supplier device package 25-WLP), the part suits space-constrained portable designs where board area is at a premium. Surface-mount assembly is standard for this WLP package; the 0.4 mm ball pitch requires a controlled solder-paste stencil and reflow profile per Maxim's application note.","metaTitle":"MAX77301AEWA+ Smart Power Selector, Li-Ion Charger, 900mA","metaDescription":"MAX77301AEWA+ battery management IC, 1-cell Li-Ion, 900mA charge current, I²C/USB interface, 25-WLP package.
