DESCRIPTION  
–
Programmable Termination and Precharge  
Threshold  
The bq2409x series of devices are highly integrated  
Li-ion and Li-Pol linear chargers devices targeted at  
space-limited portable applications. The devices  
operate from either a USB port or AC adapter. The  
high input voltage range with input overvoltage  
protection supports low-cost unregulated adapters.

–
6.6V Over-Voltage Protection  
Input Voltage Dynamic Power Management  
125°C Thermal Regulation; 150°C Thermal  
Shutdown Protection  
The bq2409x has a single power output that charges  
the battery. A system load can be placed in parallel  
with the battery as long as the average system load  
does not keep the battery from charging fully during  
the 10 hour safety timer.

–
OUT Short-Circuit Protection and ISET  
Short Detection  
Operation Over JEITA Range via Battery  
NTC – ½ Fast-Charge-Current at Cold,  
4.06V at Hot, bq24092/3  
The battery is charged in three phases: conditioning,  
constant current and constant voltage. In all charge  
phases, an internal control loop monitors the IC  
junction temperature and reduces the charge current  
if an internal temperature threshold is exceeded.
