Single-cell Li-Ion charger with I²C programmability
The Texas Instruments BQ24262RGET is a single-cell Li-Ion battery charger IC in a 24-VQFN Exposed Pad package (4x4 mm). It integrates a programmable constant-current charge engine with a maximum charge current of 3 A, controlled via an I²C interface.
The 3 A maximum charge current suits single-cell Li-Ion packs in portable equipment, power tools, or handheld instruments where charge time matters. The I²C interface allows the system host to adjust the charge current dynamically — useful for thermal management or charging from a current-limited USB source. The programmable current feature means no external resistor-divider is needed for current set-point; the host writes the target via I²C. Over-temperature and over-voltage protection are built in, reducing external component count for battery safety compliance. The 6 V maximum supply voltage covers standard 5 V USB and 5 V wall-adapter rails with margin.
Obsolete — sourcing through independent distribution
The BQ24262RGET carries an obsolete product status. No official successor or drop-in replacement is listed on the record.
