    CXLB74133 is power management solution for portable battery charger system. The device contains a full-featured battery charger with up to 2A charge current, a 2.4A output and battery protection functions. Charge mode: The charger can be powered from 5V wall adaptor with ±10% variation whereas over voltage lock out protects internal circuit during voltage surge. The device automatically turns-off charging and bypassing function when input voltage exceeds 6.1V, and can sustain up to 10V continuous input voltage with charging and bypassing function in OFF status. The device has a preset battery float voltage of 4.2V/4.35V programmable by external resistor with ±1% accuracy at room temperature. The integrated charger minimizes the charger’s physical footprint, maximizes charge efficiency, which reduces the power dissipation during charge. Discharge mode: The system power the output with 2.4A capacity. In both charge and discharge mode, PFM is engaged to maintain high efficiency at light load. CXLB74133 guarantee robustness with short-circuit protection, thermal protection, and input under and over voltage lockout. They are available in a 24-pin FCQFN4X4 package with exposed pad for low thermal resistance.
