5 Description (Continued)

The power path management feature allows the bq24250C to power the system from a high efficiency DC/DC

converter while simultaneously and independently charging the battery. The charger monitors the battery current

at all times and reduces the charge current when the system load requires current above the input current limit.

This allows for proper charge termination and enables the system to run with a defective or absent battery pack.

Additionally, this enables instant system turn-on even with a totally discharged battery or no battery. The power-

path management architecture also permits the battery to supplement the system current requirements when the

adapter cannot deliver the peak system currents. This enables the use of a smaller adapter.

The battery is charged in four phases: trickle charge, pre-charge, constant current and constant voltage. In all

charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if

the internal temperature threshold is exceeded. Additionally, a voltage-based battery pack thermistor monitoring

input (TS) is included that monitors battery temperature for safe charging.
