It handles a single Li-Ion cell with a programmable constant-current charge up to 2A, fed from a USB or adapter input rated up to 16V. The 28-TQFN (4x4 mm) package with exposed pad keeps thermal transfer honest for the 2A charge rate — the pad needs a solid via array to the ground plane if you plan to run near the limit. ## Sourcing and lifecycle It is RoHS3 compliant. No end-of-life notice is on record.","metaTitle":"MAX8903CETI+ Li-Ion Battery Charger, 2A Max, 28-TQFN","metaDescription":"MAX8903CETI+ from Maxim Integrated: 1-cell Li-Ion charger, 2A max charge current, USB interface, 16V supply max, -40°C to 85°C, 28-TQFN.
