DESCRIPTION  
The bq24150A/1A  
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

Input Current  
The bq24150A/1A 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, bq24150A/1A  
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.
