Notes

Pins 2 and 3 are both BAT (battery positive) — they are internally connected and should both be connected to the battery.
Pins 10 and 11 are both OUT (output voltage) — they are internally connected and should both be connected to the output.
The exposed pad (EP) is connected to ground and should be soldered to a ground plane for thermal management.

Typical Application

The bq2423xH devices power the system while simultaneously and independently charging the 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 limit if the input voltage falls below a threshold, 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.

The bq24232xH is configureable to be host controlled for selecting different input current limits based on the input source connected, or a fully stand alone device for applications that do not support multiple types of input sources.
