–
Charge Voltage (4-4.512 V/cell)  
Charge Current (up to 10 A)  
Adapter Current Limit for DPM  
The bq24741/2 is a high-efficiency, synchronous  
battery charger with integrated compensation,  
offering low component count for space-constrained  
Li-ion or Li-polymer battery charging applications.  
Ratiometric charge current and voltage programming  
allows high regulation accuracies, and can be either  
hardwired with resistors or programmed by the  
system power-management microcontroller using a  
DAC or GPIOs.
