BQ24012DRCR

The BQ24012DRCR is a highly integrated Li-ion and Li-polymer Linear Charge Management Device 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. It 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.

• Reverse leakage protection prevents battery drainage
