DESCRIPTION  
The bq24155 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 bq24155 integrates a synchronous  
PWM controller, power FETs, input current sensing,  
high-accuracy current and voltage regulation, and  
charge termination, into a small WCSP package.  
Charge Current Regulation Accuracy: ±5%

Charge Rate  
The bq24155 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, bq24155  
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 compatible  
interface.
