It integrates a constant-current, constant-voltage charging algorithm with programmable charge current up to 2 A and a 4.2 V battery regulation voltage. The part accepts a supply voltage up to 16 V, covering the range of standard USB (5 V) and common 9–12 V wall adapters without an external pre-regulator. Over-voltage fault protection on the input is built in, so a transient above the 16 V absolute maximum won't cascade into the battery. ## Package, temperature grade, and board-fit The industrial temperature range is the full operating envelope; no derating is required across the band for the 2 A charge current as long as the PCB thermal resistance is managed. ## Programming and fault handling Charge current and safety timer are programmable via external resistors, giving the BOM engineer control over the charge profile without firmware. The constant-current phase is set by a resistor from the ISET pin to ground; the timer sets a maximum charge duration as a backup against a failed termination. Over-voltage protection on the input rail is the only listed fault protection — the part does not include reverse-battery or thermal regulation on the datasheet summary, so the system design should account for those at the board level if the application requires them.","metaTitle":"MAX8903GETI+ Li-Ion Battery Charger, 2A, 28-TQFN","metaDescription":"Analog Devices MAX8903GETI+ Li-Ion battery charger IC, 1-cell, 2A max charge current, USB interface, 28-TQFN.
