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.
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.
