3A I²C charger for single-cell Li-Ion packs
The Texas Instruments BQ24296RGET is an I²C-controlled, single-cell Li-Ion/Li-Pol battery charger in a 24-VQFN (4x4) package. The I²C interface lets the host system set charge parameters and read status registers — a step up from resistor-programmed chargers when the BOM needs dynamic current limiting or charge-cycle telemetry.
Input voltage ceiling and fault protection
The maximum supply voltage is 6.2 V, which covers standard 5 V USB bus power with margin for cable drop and hot-plug overshoot. The charger integrates over-current, over-temperature, and over-voltage fault protection — these are safety-level features that prevent cell stress and thermal runaway in a fault condition.
