Description
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.
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.
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.
