BQ21080YBGR TI Battery Charger IC | 8-DSBGA (1.6X1.1) | 1A Charge, I2C Control

Product Overview

The BQ21080YBGR from Texas Instruments is a highly integrated, single-cell Li-Ion and Li-Pol battery charger IC designed for space-constrained portable applications. It supports a charge current up to 1A with I2C programmable parameters, enabling flexible charging profiles. The device operates from a 3.5V to 6.2V input voltage range and includes power path management, allowing the system to run even with a deeply discharged battery. Housed in a compact 8-DSBGA (1.6mm x 1.1mm) package, it is ideal for wearables, hearables, and other small form-factor devices.
