MAXIM INTEGRATED / ANALOG DEVICES MAX8903JETIT Li+ Charger and Power Selector
The MAX8903JETI+T is an integrated 1-cell Li+ charger and smart power selector in a 28-pin TQFN package. It features dual power inputs for USB and AC adapter, utilizing a high-frequency switch mode charger to minimize heat and external components. The device supports operation with separate or combined inputs, includes on-chip power switches for charging and load switching, and protects against backflow of current when no input power is present. It provides functions such as pre-charge, fast-charging, overvoltage protection, status and fault indicators, power-OK monitoring, and battery thermistor monitoring. Thermal limiting helps prevent overheating by reducing charging and input current. The device supports a wide input voltage range (4.15V to 16V for DC, 4.1V to 6.3V for USB), with a maximum switching frequency of 4MHz. It includes an integrated current sense resistor, and allows independent setting of charge and system load current limits. Surplus system power is used to charge the battery. The component is suitable for power management in multimedia and portable devices.
