It accepts a USB or DC supply up to 16V and includes over-voltage fault protection, with programmable charge current and timer via external components. ## Charge current and battery regulation limits Maximum charge current is 2A, programmable via an external resistor — this sets the charge rate for a single 4.1V Li-ion cell, so the thermal design of the 28-TQFN package must dissipate the I²R loss at full current. The 16V supply maximum covers USB VBUS (5V nominal) and common 12V wall adapters, with headroom for transients before the over-voltage protection triggers. Programmable timer and current features let the designer tailor the charge profile to the cell capacity — a 1000 mAh cell charges at 0.5C with a 500 mA setting, while a 2000 mAh cell uses the full 2A for 1C rate.","metaTitle":"MAX8903DETI+ Analog Devices Li-Ion Charger, 2A, 28-TQFN","metaDescription":"MAX8903DETI+ single-cell Li-ion battery charger from Analog Devices. 2A programmable charge current, 16V supply max, -40 to 85°C.
