BQ24012DRCR Datasheet PDF - TI

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

● Integrated current and voltage regulation

● ±0.5% Voltage regulation accuracy

● Charge termination by minimum current and time

● Pre-charge conditioning with safety timer

● Battery insertion and removal detection

● Works with regulated and unregulated supplies

● Short-circuit protection

● Green product and no Sb/Br

●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
