Single-cell Li-Ion/Polymer power manager in a 5x5 QFN
The Texas Instruments TPS650250RHBR is a power management IC designed for single-cell Lithium Ion/Polymer battery-powered systems. It integrates charging, regulation, and protection functions into a single 32-VFQFN Exposed Pad package measuring 5x5 mm.
Protection and operating envelope
On-chip over-temperature fault protection prevents the die from exceeding safe junction limits during charging faults or sustained high-load conditions — a practical safeguard for designs where the battery pack is not separately monitored. The 32-VQFN (5x5 mm) exposed-pad package requires a thermal land pattern on the PCB to pull heat from the die into the board copper. Layout engineers should budget a solid ground-plane connection under the pad and a via array to the inner layers.
That means it remains eligible for new designs and standard-channel replenishment without LTB risk. For dual-sourcing resilience, evaluate the broader TPS650250 family (base product number TPS650250) for package-compatible variants, but confirm the specific feature set against the BOM.
