Product details

Active production — single-cell Li-Ion charger with USB interface

The BQ24167YFFT is an active-production single-cell Li-Ion battery charger IC from Texas Instruments, designed for USB-powered portable equipment. The IC integrates over-temperature and short-circuit fault protection, reducing external component count for the protection loop.

2.5 A programmable charge current in a 2.8x2.8 mm DSBGA

Housed in a 49-DSBGA package measuring 2.8x2.8 mm, the BQ24167YFFT fits space-constrained designs such as wearable or handheld devices. The 2.5 A max charge current supports fast charging of a single-cell Li-Ion pack, but the thermal budget at that current must be evaluated against the board copper area — the DSBGA relies on the PCB pad for heat spreading. The USB interface allows direct connection to a USB VBUS rail, simplifying the input power path for portable gear.

Industrial temperature grade and surface-mount assembly

Surface-mount assembly is standard for the DSBGA package — a solder-paste stencil and reflow profile matching the pitch are required.

Frequently asked questions

Can BQ24167YFFT charge a 2-cell Li-ion battery pack?

No — the BQ24167YFFT is a single-cell charger with a 3.7 V battery pack voltage target. For a 2-cell pack you would need a charger IC designed for series-cell topologies, such as the BQ24170 or BQ24133 family.

Is BQ24167YFFT compatible with USB Type-C?

The interface is listed as USB, which covers standard USB 2.0/3.0 VBUS (5 V). USB Type-C compatibility depends on the input power negotiation — the BQ24167YFFT does not include Type-C CC logic; a separate CC controller or PD PHY would be needed upstream if Type-C negotiation is required.

How do I program the charge current on BQ24167YFFT?

The charge current is constant and programmable — typically set via an external resistor from the ISET pin to ground. The resistor value determines the charge current up to the 2.5 A maximum. Refer to the datasheet for the exact resistor calculation formula.
