That removes the BOM cost of external resistor dividers and trim pots, and lets the firmware adapt the charge profile to different battery packs detected at power-up. Over-voltage fault protection is built in, so a failed I²C write or a stuck bus won't send the pack to overvoltage. ## Package and mounting — 24-TQFN with exposed pad The 24-TQFN (4x4 mm body) is a surface-mount part that needs the center pad soldered to a PCB copper plane for thermal and electrical ground connection. The supplier device package designation confirms the same footprint. For a 7A charger, the PCB layout should use multiple vias under the pad to conduct heat to inner layers. The exposed pad also carries the ground return for the high-current charge path. ## Lifecycle and sourcing reality For BOM planning, this is a stable line item you can qualify into production without worrying about a last-time-buy window.","metaTitle":"MAX17435ETG+ battery charger IC, 2-4 cell Li-ion, 7A, I²C","metaDescription":"MAX17435ETG+ multi-chemistry battery charger IC from Maxim Integrated.
