DESCRIPTION
The bq24702/bq24703 is a highly integrated battery charge controller and selector tailored for notebook and sub-notebook PC applications. The bq24702/bq24703 uses dynamic power management (DPM) to minimize battery charge time by maximizing use of available wall-adapter power. This is achieved by dynamically adjusting the battery charge current based on the total system (adapter) current.

FEATURES
Dynamic Power Management, DPM Minimizes Battery Charge Time
Integrated Selector Supports Battery Conditioning and Smart Battery Learn Cycle
Zero Volt Operation
Selector Feedback Circuit Ensures Break-Before-Make Transition
±0.4% Charge Voltage Accuracy, Suitable for Charging Li-Ion Cells
±4% Charge Current Accuracy
300-kHz Integrated PWM Controller for High-Efficiency Buck Regulation
Depleted Battery Detection and Indication to Protect Battery From Over Discharge
20-µA Sleep Mode Current for Low Battery Drain
24-Pin TSSOP Package and 5 mm ×5 mm QFN package (bq24703 only)
