DESCRIPTION  
The bq24150/1 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

current sensing, high-accuracy current and voltage  
regulation, and charge termination, into a small  
WCSP package.

Input Current  
The bq24150/1 charges the battery in three phases:  
conditioning, constant current and constant voltage.  
The input current is automatically limited to the value  
set by the host. Charge is terminated based on  
user-selectable minimum current level. A safety timer  
with reset control provides a safety backup for I2C  
interface. During normal operation, bq24150/1  
automatically restarts the charge cycle if the battery  
voltage falls below an internal threshold and  
automatically enters sleep mode or high impedance  
mode when the input supply is removed. The charge  
status is reported to the host using the I2C interface.
