Power management IC for portable and battery systems
The Texas Instruments TPS658600ZQZT is a power management IC targeting battery management, display LED drivers, handheld/mobile devices, and general power supply applications. It integrates multiple voltage rails and control functions into a single 120-VFBGA package (6x6 mm Microstar Junior), reducing board area in space-constrained designs. The supply range spans 3 V to 18 V, covering single-cell Li-ion through multi-cell battery stacks and regulated 12 V rails. Quiescent current is 870 µA, a key parameter for extending battery run time in always-on handheld equipment.
The 120-VFBGA (120-ball fine-pitch BGA) with a 6x6 mm body requires careful fan-out planning. The 0.50 mm ball pitch typically demands micro-vias or blind vias on a 4-layer PCB to route all signals without excessive via-in-pad. The supplier device package is 120-BGA Microstar Junior (6x6). Surface-mount only.
It is not specified for extended automotive under-hood or military environments.
