Product details

2.2 A charger for 2-cell Li-Ion packs

The BQ25886RGET is a constant-current Li-Ion/Polymer charger from Texas Instruments, designed for 2-cell series stacks with a maximum battery pack voltage of 9.2 V. It delivers up to 2.2 A charge current from a USB supply, with the input voltage ceiling at 6.2 V.

Industrial temp and fault protection

On-chip fault protection includes over-current, over-temperature, over-voltage, and short-circuit detection — the charger shuts down autonomously before the external MOSFET or inductor sees stress.

Frequently asked questions

What is the maximum charge current for BQ25886RGET?

2.2 A maximum charge current, constant-current profile. The actual charge rate is programmable via the I2C interface, so the 2.2 A ceiling is the hardware limit — the firmware sets the target.
