The Texas Instruments TPS650245RHBT is a power-management IC designed for single-cell Lithium Ion/Polymer battery-powered systems. It integrates the charging and system power-rail sequencing into one 32-VFQFN Exposed Pad package, which keeps the BOM count low in portable devices like handheld instruments, medical monitors, and IoT edge nodes that run on one Li-Ion cell. The part carries over-temperature and under-voltage fault protection, so the battery stays within safe operating bounds during charge and discharge. That matters when the end product goes through outdoor temperature swings or sits in a sealed enclosure where a runaway cell is not an option.
A handheld field instrument or a battery-backed sensor node in a telecom cabinet lives inside this range without needing an automotive-grade derating.
Without that via stitch the junction temperature climbs faster during continuous charge current — the pad is the primary dissipation path, not the package body.
It is ROHS3 compliant, which clears the regulatory gate for EU-market builds without an exemption review.
