bq24703 MULTICHEMISTRY BATTERY CHARGER CONTROLLER AND SYSTEM POWER SELECTOR

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 t.
