Product details

Single-cell Li-Ion charger with 2.5 A ceiling

The Texas Instruments BQ24167RGER is a single-cell Lithium Ion battery charger IC designed for portable devices that charge from a USB source. It delivers a programmable constant charge current up to 2.5 A max, sized for single-cell 3.7 V battery packs in power banks, handheld instruments, and IoT edge nodes.

Charge current programming and protection

Charge current is constant and programmable, so the BOM resistor or firmware sets the rate per the battery capacity. The 2.5 A ceiling supports fast charging for cells rated at 2500 mAh or higher, but the thermal budget in the 24-VFQFN package with exposed pad must be checked against the PCB copper area. On-chip fault protection covers over-temperature and short-circuit conditions, which is the safety layer that prevents thermal runaway during a fault event.

USB input and temperature range

The USB interface means the charger accepts 5 V from a standard USB port or adapter, with a maximum supply voltage of 10 V.

Frequently asked questions

Is BQ24167RGER obsolete or end-of-life?

No, the BQ24167RGER is listed with an active lifecycle status.

What is the recommended charge current programming method for BQ24167RGER?

The charge current is constant and programmable, typically set by an external resistor connected to the ISET pin. The maximum charge current is 2.5 A, and the actual current is programmed by selecting the resistor value per the formula in the datasheet.

Is BQ24167RGER compatible with a single 3.7V lithium battery?

Yes, the BQ24167RGER is designed for single-cell Lithium Ion batteries with a nominal voltage of 3.7 V. It charges a single cell and includes over-temperature and short-circuit protection for safe operation.

Does BQ24167RGER have a lead-free/RoHS package?

The BQ24167RGER ships in a Tape & Reel package, which is standard for RoHS-compliant surface-mount components. The 24-VFQFN Exposed Pad package is lead-free compatible per TI's standard green packaging.
