MAXIM INTEGRATED / ANALOG DEVICES MAX8903CETI Lithium-Ion Charger
The MAX8903CETI+ is an integrated single-cell lithium-ion battery charger and smart power selector, available in a 28-pin TQFN package. It features dual input sources—USB and AC adapter—and uses a high switching frequency to reduce heat and minimize external components. The device can operate from separate or combined inputs, with on-chip power switches managing charging and load switching between battery and external power. It includes functions such as pre-qualification charging, fast charging, overvoltage protection, charge status indicators, fault monitoring, power-OK monitoring, and battery thermistor measurement. Internal thermal management reduces charging and current draw to prevent overheating. Key features include optimized power control via USB or adapter, input voltage ranges of 4.15V to 16V (DC) and 4.1V to 6.3V (USB), a maximum switching frequency of 4MHz, and an integrated current sense resistor with a system switch resistance of 50 milliohms. The charger supports independent current limit settings for battery charge and system load, and any unused power is directed to charge the battery. No external MOSFETs or diodes are required, making it a compact solution suitable for power management in multimedia and portable devices.
