bq24703 www.ti.com SLUS553E–MAY 2003–REVISED OCTOBER 2007 MULTICHEMISTRY BATTERY CHARGER CONTROLLER AND SYSTEM POWER SELECTOR 1 FEATURES DESCRIPTION • Dynamic Power Management, DPM Minimizes Battery Charge Time The bq24702/bq24703 is a highly integrated battery • Integrated Selector Supports Battery charge controller and selector tailored for notebook and sub-notebook PC applications. Conditioning and Smart Battery Learn Cycle • Zero Volt Operation The bq24702/bq24703 uses dynamic power management (DPM) to minimize battery charge time • Selector Feedback Circuit Ensures by maximizing use of available wall-adapter power. Break-Before-Make Transition This is achieved by dynamically adjusting the battery • ±0.4% Charge Voltage Accuracy, Suitable for charge current based on the total system (adapter) Charging Li-Ion Cells current. • ±4% Charge Current Accuracy The bq24702/bq24703 uses a fixed frequency, pulse • 300-kHz Integrated PWM Controller for width modulator (PWM) to accurately control battery High-Efficiency Buck Regulation charge current and voltage. Charge current limits can be programmed from a keyboard controller DAC or • Depleted Battery Detection and Indication to by external resistor dividers from the precision 5-V, Protect Battery From Over Discharge ±0.6%, externally bypassed voltage reference • 20-μA Sleep Mode Current for Low Battery (VREF), supplied by the bq24702/bq24703.
