2A charge current, I²C-controlled
The BQ24253YFFT is a single-cell Li-Ion battery charger IC from Texas Instruments, delivering a programmable charge current up to 2A. The I²C interface lets firmware set the charge current in real time, so you can adjust the charging profile without a hardware resistor change.
Input voltage ceiling and protection
Maximum supply voltage is 10.5V, which covers standard 5V USB and 9V adapters with margin. Built-in fault protection against over-current, over-voltage, and over-temperature reduces the need for external supervisory components.
Industrial temperature range, 30-DSBGA package
The 30-DSBGA package is a 0.4mm-pitch wafer-level chip-scale package — the small footprint saves board space, but the fine pitch demands a controlled assembly process and a solder mask defined pad layout.
