Texas Instruments BQ24083 1-cell Li-Ion Charger w/ 4.06V Charge Voltage BQ24083DRCT

The BQ24083DRCT is a highly integrated linear charger designed for single-cell Li-Ion and Li-Polymer batteries, offering a charge voltage option of 4.06V or 4.2V. It supports a maximum charge current of 1A and features an integrated power FET and current sensor for efficient operation. The device operates in three charging phases: conditioning, constant current, and constant voltage, with charge termination based on minimum current detection. An internal safety timer ensures reliable charge termination, while the charger automatically restarts if the battery voltage drops below a specified threshold. The BQ24083DRCT also includes a sleep mode for low power consumption when the AC adapter is disconnected. Its compact 3-mm x 3-mm SON package makes it suitable for space-constrained applications such as PDAs, MP3 players, digital cameras, and smartphones. The operating temperature range is from -40¬8C to 125¬8C, making it versatile for various environments.
