The 24-VFQFN (4x4 mm) package with exposed pad suits space-constrained portable designs where thermal dissipation through the PCB is critical. ## 2A charge current and fault protection The constant-current charge profile is programmable via I²C, with a maximum charge current of 2A. The battery regulation voltage is fixed at 4.2V, matching standard single-cell Li-Ion termination. On-chip fault protection covers over-current, over-temperature, and over-voltage conditions, reducing the need for external supervisory circuits. The maximum supply voltage is 10.5V, covering standard 5V USB and 9V wall-adapter inputs without an external pre-regulator. ## Active lifecycle and ordering options It is offered in Tape & Reel (TR) for automated assembly and Cut Tape (CT) for prototype or low-volume builds.","metaTitle":"BQ24253RGER I²C Li-Ion Charger, 2A Max, 24-VQFN","metaDescription":"Texas Instruments BQ24253RGER single-cell Li-Ion charger with I²C interface, 2A max charge current, fault protection, -40°C to 85°C, 24-VQFN.
