Overview
The BQ24160RGER, produced by Texas Instruments, is a highly integrated single-cell Li-ion battery charger and system power path management device. It is designed for space-limited, portable applications with high-capacity batteries. This device features dual inputs, allowing operation from either a USB port or a higher-power input supply such as an AC adapter or wireless charging input. The power path management feature enables the system to run with a defective or absent battery pack and allows instant system turn-on even with a totally discharged battery or no battery.
