BQ24080 详细介绍

BQ24080 描述

The BQ24080 and BQ24081 are highly integrated and flexible Li-Ion linear charge devices targeted at space-limited charger applications. BQ24080 offer an integrated power FET and current sensor, high-accuracy current and voltage regulation, charge status, and charge termination, in a single monolithic device. BQ24080 An external resistor sets the magnitude of the charge current. TheBQ24080  charges the battery in three phases: conditioning, constant current, and constant voltage. Charge is terminated based on minimum current. BQ24080 An internal charge timer provides a backup safety for charge termination. The BQ24080 automatically restarts the charge if the battery voltage falls below an internal threshold. The BQ24080 automatically enters sleep mode when the ac adapter is removed
