Product details

Single-cell Li-Ion charger with I²C programmability

The Texas Instruments BQ24168RGER is a single-cell Lithium Ion/Polymer battery charger IC with an I²C interface, delivering a programmable constant charge current up to 2.5 A max. It integrates over-voltage and over-temperature fault protection, reducing the need for external supervisory components.

The 2.5 A max charge current suits single-cell Li-Ion packs in portable devices, power tools, or medical gear where fast charging is needed. The I²C interface lets firmware set the charge current, termination voltage, and safety timers, and read back status flags — no external resistors for current programming.

Frequently asked questions

Is BQ24168RGER compatible with 2-cell batteries?

No — the BQ24168RGER is designed for single-cell (1S) Lithium Ion/Polymer packs only. The battery pack voltage is 3.7 V nominal, and the maximum supply voltage is 6 V. It does not support 2-cell (2S) configurations.
