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.","metaTitle":"BQ24167YFFT Texas Instruments Li-Ion Charger IC – Active","metaDescription":"BQ24167YFFT single-cell Li-Ion charger IC from TI, 2.5A max charge current, USB interface, -40°C to 85°C, 49-DSBGA.

For a 2-cell pack you would need a charger IC designed for series-cell topologies, such as the BQ24170 or BQ24133 family."},{"question":"Is BQ24167YFFT compatible with USB Type-C?","answer":"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."},{"question":"How do I program the charge current on BQ24167YFFT?","answer":"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.
