产品概述
The bq24080 and bq24081 are highly integrated and flexible Li-Ion linear charge devices
targeted at space-limited charger applications. They offer an integrated power FET and current
sensor, high-accuracy current and voltage regulation, charge status, and charge termination, in a
single monolithic device. An external resistor sets the magnitude of the charge current. The device charges the battery in three phases: conditioning, constant current, and
constant voltage. Charge is terminated based on minimum current. An internal charge timer provides
a backup safety for charge termination. The device automatically restarts the charge if the battery
voltage falls below an internal threshold. The device automatically enters sleep mode when the ac
adapter is removed.
