The PCB land pattern must follow the TI-recommended footprint. ## 300 mA charge current and 4.65 V termination This is a linear charger for a single Li-Ion cell, rated for a maximum charge current of 300 mA and a maximum battery regulation voltage of 4.65 V. The I²C interface lets the host set the exact regulation point via the programmable current and voltage registers. ## Industrial temperature range and fault protection On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions. The supply input accepts up to 5.5 V.","metaTitle":"BQ25122YFPT I²C Li-Ion Charger, 300mA, 25-DSBGA","metaDescription":"Texas Instruments BQ25122YFPT single-cell Li-Ion linear charger with I²C interface.
