Product Description

The BQ24270RGET is a Li-ion Battery Charger with power path management and I2C interface. It is targeted for space-limited, portable applications with high capacity batteries. The single cell charger has several input current limits which allow operation from either an USB port or higher power input supply (i.e. AC adapter or wireless charging input) for a versatile solution. The power path management feature allows the BQ24270 to power the system from a high efficiency DC to DC converter while simultaneously and independently charging the battery. The charger monitors the battery current at all times and reduces the charge current when the system load requires current above the input current limit. This allows for proper charge termination and timer operation. The system voltage is regulated to the battery voltage but will not drop below 3.5V.
