Product details

Single-cell Li-Ion charger with I²C control and 1.5A ceiling

The Texas Instruments BQ24185YFFR is a single-cell Li-Ion/Polymer battery charger IC in a 25-bump DSBGA package. It accepts up to 16 V on the input and delivers a programmable constant charge current up to 1.5 A via I²C control.

Charge current programming and fault protection

Charge current is set through the I²C interface — no external resistor needed for the current setpoint. The charger integrates over-temperature and over-voltage fault protection, and includes a programmable timer for charge termination.

Frequently asked questions

Is BQ24185YFFR suitable for a 4.2V Li-ion battery?

Yes. The maximum battery pack voltage is 4.44 V, which covers the standard 4.2 V Li-ion termination voltage with margin.

How do I program the charge current on BQ24185YFFR?

The charge current is set via the I²C interface using the device's internal registers. No external programming resistor is required.
