bq24702 Datasheet Multichemistry Battery Charger Controller And System Power Selector

Manufacturer: Texas Instruments

Overview: www.ti.com Actual Size (6,60 mm x 7,90 mm) bq24702 bq24703 SLUS553E – MAY 2003 – REVISED OCTOBER 2007 MULTICHEMISTRY BATTERY CHARGER CONTROLLER AND SYSTEM POWER.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The bq24702/bq24703 is a highly integrated battery charge controller and selector tailored for notebook and sub-notebook PC applications.

The bq24702/bq24703 uses dynamic power management (DPM) to minimize battery charge time by maximizing use of available wall-adapter power.

This is achieved by dynamically adjusting the battery charge current based on the total system (adapter) current.
