Battery Charger Li-Ion/Li-Pol 1000mA 4.2V 10-Pin VSON EP T/R, BQ24013DRCR, Texas Instruments

Описание

The bqTINY series are highly integrated Li-Ion and Li-Pol linear charge management devices targeted at space limited portable applications. The bqTINY series offer integrated powerFET and current sensor, reverse blocking protection, high accuracy current and voltage regulation, charge status, and charge termination, in a small package.The bqTINY 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 feature for charge termination. The bqTINY automatically restarts the charge if the battery voltage falls below an internal threshold. The bqTINY automatically enters sleep mode when VCC supply is removed.In addition to the standard features, different versions of the bqTINY offer a multitude of additional features. These include temperature sensing input for detecting hot or cold battery packs; power good (PG) output indicating the presence of valid input power; a TTL-level charge-enable input (CE) used to disable or enable the charge process; and a TTL-level timer and termination enable (TTE) input used to disable or enable the fast-charge timer and charge termination.
