Single-cell Li-Ion charger with USB input and 3A capability
Charge current and input voltage — sizing the power path
The 3A maximum charge current suits single-cell Li-Ion packs in tablets, power banks, and handheld instruments where charge time matters. The 14V maximum supply voltage covers standard USB and 5V adapters, but the input must be protected against transients above that ceiling — a TVS clamp on the VBUS line is recommended. The constant-current charging mode is programmable via an external resistor (ISET pin), letting the designer trade charge speed against thermal budget.
The BQ24266RGET is officially obsolete per Texas Instruments' product lifecycle status. No direct replacement or successor order code is listed on the record.
