9.1 Overview

The bq2407x devices are integrated Li-Ion linear chargers and system power path management devices targeted

at space-limited portable applications. The device powers the system while simultaneously and independently

charging the battery. This feature reduces the number of charge and discharge cycles on the battery, allows for

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

also allows instant system turn-on even with a totally discharged battery. The input power source for charging the

battery and running the system can be an AC adapter or a USB port. The devices feature Dynamic Power Path

Management (DPPM), which shares the source current between the system and battery charging, and

automatically reduces the charging current if the system load increases. When charging from a USB port, the

input dynamic power management (VIN-DPM) circuit reduces the input current if the input voltage falls below a

threshold, thus preventing the USB port from crashing. The power-path architecture also permits the battery to

supplement the system current requirements when the adapter cannot deliver the peak system currents.
