It integrates an over-voltage protection block, so a fault on the input rail does not propagate to the battery or the system rail. ## Key charging parametrics for the BOM The charge current is programmable up to 2 A maximum, with a constant-current phase that the designer sets via an external resistor — the 2 A ceiling governs the thermal budget in the 28-TQFN package. Battery regulation voltage is 4.35 V, the termination voltage for a 1-cell Li-Ion stack; the charger enters constant-voltage mode at this threshold and holds it until the charge current tapers to the programmed termination level. Supply voltage rating is 16 V maximum, which covers the full USB bus-voltage range plus margin for hot-plug transients on the VBUS line. Programmable features include the charge current and a safety timer — the timer provides a backup termination if the battery fails to reach the regulation voltage within the set window, a standard safeguard for Li-Ion charging. ## Compliance and procurement posture ROHS3 compliant per the manufacturer's declaration, covering the full substance-restriction scope of the EU RoHS directive.","metaTitle":"Analog Devices MAX8903JETI+T Li-Ion Charger, 2A, 28-TQFN","metaDescription":"Active production Li-Ion battery charger IC from Analog Devices. 1-cell, 2A max charge current, 16V supply max, -40°C to 85°C. 28-TQFN package.
