Description

The bq2501x series are highly integrated charge andpower management devices targeted at space-limited bluetooth applications. The bq2501x series offer integrated power FET and current sensor for charge control, reverse blocking protection, high accuracy current and voltage regulation, charge status, charge termination, and a highly efficient and low-power dc-dc converter in a small package.

The bq2501x 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 bq2501x automatically re-starts the charge if the battery voltage falls below an internal threshold.
