bq2407xT 1.5A USB-Friendly Li-Ion Battery Charger and Power-Path Management IC Features 3 DescriptionThe bq2407xT seriesof devices are integrated Li-ion Fully Compliant USB Charger linear chargers and system power path management• Selectable 100mA and 500mA Maximum Input devices targeted at space-limited portableCurrent applications. The devices operate from eithera USB 100mA Maximum Current Limit Ensures portor AC adapter and support charge currents upto
1.5A. The input voltage range with input over-voltageComplianceto USB-IF Standard
protection supports unregulated adapters. The USB• Input based Dynamic Power Management (VIN- input current limit accuracy and start up sequenceDPM) for Protection Against Poor USB Sources allow the bq2407xTto meet USB-IF inrush current• 28V Input Rating with Over-voltage Protection specification. Additionally, the input dynamic power Integrated Dynamic Power Path Management management (VIN- DPM) prevents the charger from
crashing incorrectly configure USB sources.(DPPM) Function Simultaneously and
Independently Powers the System and Charges
