PMIC for portable equipment — now obsolete
The Texas Instruments TPS6591102AA2ZRC is a power management IC (PMIC) designed for portable equipment, integrating multiple voltage rails and system control functions in a single 98-BGA MICROSTAR JUNIOR package. The official lifecycle status is Obsolete, meaning TI no longer manufactures this exact order code.
The 2.7V to 5.5V supply window covers single-cell Li-ion (3.0V–4.2V) and two-cell alkaline (3.0V) down to the battery cutoff, so any replacement must match this input range to avoid a power-rail redesign.
98-BGA MICROSTAR JUNIOR — layout and rework considerations
The 98-BGA MICROSTAR JUNIOR (9x6 mm) is a fine-pitch BGA. The BGA footprint is the constraint for any pin-compatible replacement search.
