2-cell Li-Ion charger with I²C control and 2.2 A fast charge
The Texas Instruments BQ25883RGET is a 2-cell Li-Ion/Polymer battery charger IC with a max charge current of 2.2 A and a max battery pack voltage of 9.2 V. It uses an I²C and USB interface for digital control and input power routing, making it a fit for portable devices, power tools, and IoT gadgets that need a fast, programmable charge profile for a two-cell series stack.
Protection suite and temperature grade
Built-in fault protection covers overcurrent, overtemperature, overvoltage, and short circuit conditions — the IC handles the safety checks autonomously, reducing external component count.
Housed in a 24-VFQFN Exposed Pad package (supplier device package 24-VQFN 4x4 mm), the part is surface-mount and hand-solderable with a hot-air station or reflow profile.
