Product details

It uses an I²C interface for programming charge current, termination voltage, and status monitoring, making it suitable for portable devices where the host processor manages the charging profile. The charger supports a constant-current / constant-voltage (CC/CV) algorithm with a programmable charge current up to 2.5A and a fixed battery regulation voltage of 4.2V.

Input voltage and fault protection

The device accepts a maximum supply voltage of 17V, which covers standard USB inputs (5V) and common wall adapters up to 12V with margin. Integrated fault protection includes over-current, over-temperature, and over-voltage detection, reducing external component count and simplifying the safety compliance path.

Housed in a 24-VFQFN Exposed Pad package (4x4 mm body, supplier device package 24-VQFN), the BQ24196RGET requires a surface-mount reflow process.

Frequently asked questions

Is BQ24196RGET compatible with 4.2V Li-ion batteries?

Yes, the battery pack voltage is fixed at 4.2V, which is the standard termination voltage for single-cell Li-Ion and Li-Polymer cells.
