It delivers a programmable charge current up to 300 mA. ## 300 mA charge current — what it means for your BOM The 300 mA maximum charge current sets the charge time for a given cell capacity. This part is sized for small-capacity cells typical of hearables, smartwatches, and medical patches. ## I²C programmable features Both charge current and battery regulation voltage are programmable through the I²C interface, alongside GPIO lines for status or control. The 4.6 V max battery voltage suits high-voltage Li-Poly cells common in thin devices. ## Package and mounting The 30-WLP (wafer-level package) measures 2.75 x 2.15 mm — essentially the die size. That is the smallest footprint you will find for a charger IC with this feature set, but it comes with trade-offs: no leads to inspect, and rework requires a hot-air station with a fine nozzle. The land pattern is the WLP ball array; verify the PCB pad layout against the package drawing before committing the board. Surface-mount only, supplied in Tape & Reel. ## Lifecycle and compliance ROHS3 compliant — no exemptions to track.","metaTitle":"MAX77651AEWV+T Li-Ion Battery Charger IC, 300mA, 30-WLP","metaDescription":"MAX77651AEWV+T single-cell Li-Ion/Polymer charger IC from Analog Devices. 300 mA max charge current, I²C programmable, 30-WLP package.
