Single-cell Li-Ion/Power manager with I²C and USB
The Texas Instruments TPS65013RGZR is a multi-function controller integrating battery charging, power-path management, and voltage regulation for single-cell Lithium Ion/Polymer designs. It communicates over I²C for system configuration and monitoring, and includes a USB interface for charging port negotiation — common in handheld medical, industrial portable, and IoT edge devices that need to run from a battery while staying connected to a USB host.
If your system charges a Li-Po pack in a heated enclosure but the PCB sits in an unheated warehouse at -20°C, this part keeps the charge algorithm and I²C bus alive without a separate heater.
Surface-mount assembly with a 0.50 mm pitch; the 48-VQFN (7x7) supplier package footprint is standard for this class of power-management IC.
