Product details

The BQ24272YFFR is a single-cell Li-Ion battery charger from Texas Instruments that delivers a programmable constant charge current up to 2A. The I²C interface lets the host controller set the charge current and termination voltage dynamically, which is useful for multi-chemistry support or thermal throttling in compact enclosures.

Fault protection and thermal envelope

Integrated over-temperature, over-voltage, and short-circuit protection are on-die, so no external supervisor IC is needed for safe single-cell charging.

The base product number BQ24272 covers a family of variants; confirm the YFFR suffix for the 49-DSBGA tape-and-reel ordering code.

Frequently asked questions

What is the maximum charge current for BQ24272YFFR?

The maximum charge current is 2A, programmable via the I²C interface. The actual charge current in a design will depend on the input power source, thermal budget, and battery impedance.

Does BQ24272YFFR support I²C interface?

Yes, the charge current and voltage setpoints are controlled through an I²C interface, allowing the host processor to read status registers and adjust the charging profile in real time.
