Power management IC for handheld and mobile designs
The Texas Instruments TPS658643ZQZR is a power management IC (PMU) designed for handheld and mobile devices. It integrates multiple voltage rails and system control functions needed to run a portable product from a single battery or USB input. The input supply range spans 3V to 5.5V, covering a single-cell Li-ion through USB VBUS without an external pre-regulator. That extra margin matters if the device spends time in a hot car dashboard, a cold-weather field terminal, or an industrial handheld that sees outdoor storage.
120-ball BGA — board and rework planning
That 6x6 mm body with 0.5 mm ball pitch typical for this class means a 4-layer PCB is the practical minimum for fan-out; two-layer boards will struggle to route all balls without buried vias. The Microstar Junior package has a thinner core than a standard BGA, so the moisture sensitivity level and bake profile before reflow should be confirmed from the latest TI document. Shipping in Tape & Reel (TR) format, which is the standard feeder-ready presentation for the 120-VFBGA. No tray or tube option listed — plan for reel-fed pick-and-place.
The TPS658643ZQZR carries an official product status of Obsolete. The base product number TPS658 covers a family of PMUs, but without a specific TI-recommended successor order code, any substitution requires a full pin-to-pin and register-map comparison against the original BOM.
