|Description:||TI's BQ24702/3 Multichemistry Batter Charger Controller ans System Poer Selector|
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. The bq24702/bq24703 uses a fixed frequency, pulse
width modulator (PWM) to accurately control battery charge current and voltage. Charge current limits can
be programmed from a keyboard controller DAC or by external resistor dividers from the precision 5-V, ±0.6%,
externally bypassed voltage reference (VREF), supplied by the bq24702/bq24703.
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-uA Sleep Mode Current for Low Battery Drain 24-Pin TSSOP Package and 5 mm × 5 mm QFN package (bq24703 only) Please send any comments to: email@example.com
