DESCRIPTION  
The  
bq24153/6/8  
is  
a
compact,  
flexible,  
high-efficiency, USB-friendly switch-mode charge  
management device for single-cell Li-ion and  
Li-polymer batteries used in a wide range of portable  
applications. The charge parameters can be  
programmed through an I2C interface. The IC  
integrates a synchronous PWM controller, power  
MOSFETs, input current sensing, high-accuracy  
current and voltage regulation, and charge  
termination, into a small WCSP package.  
•
•
Synchronous Fixed-Frequency PWM  
Controller Operating at 3 MHz With 0% to  
99.5% Duty Cycle  
Automatic High Impedance Mode for Low  
Power Consumption
