BQ24013

采用 QFN/MLP-10 封装的 bqTINYTM 线性 1 节 4.2V 锂离子充电器，具有 1A FET 和充电终止使能端

The bqNY™ 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.
