Product details

Single-cell Li-Ion charger with USB input and 3A capability

The Texas Instruments BQ24266RGET is a single-cell lithium-ion battery charger IC designed for USB-powered portable devices. It delivers a programmable constant charge current up to 3A to a 4.2V battery pack, with integrated over-temperature and over-voltage fault protection.

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.

Obsolete — sourcing through independent distribution

The BQ24266RGET is officially obsolete per Texas Instruments' product lifecycle status. No direct replacement or successor order code is listed on the record.
