The bq24083 is highly integrated and flexible Li-Ion linear charge device targeted at space-limited charger applications. It offers 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 bq24083 has an option of two output battery charge voltages: 4.06 V and 4.2 V.

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.
