The bq24704 is  
a high-efficiency, synchronous  
battery charger with integrated compensation offering  
low component count for space-limited Li-Ion and  
Li-Polymer battery charging applications. 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.
