Dynamic Power Management, DPM  
Minimizes Battery Charge Time  
The bq24702/bq24703 is a highly integrated battery  
charge controller and selector tailored for notebook and  
sub-notebook PC applications.  
Integrated Selector Supports Battery  
Conditioning and Smart Battery Learn Cycle  
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.

0.4% Charge Voltage Accuracy, Suitable for  
Charging Li-Ion Cells  
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.
