It integrates a slew-rate controlled turn-on to limit inrush current, which is useful when switching capacitive loads or hot-swapping peripheral rails. The switch is non-inverting, with a simple On/Off interface, and requires no external Vcc/Vdd supply — it powers directly from the load rail.
Housed in a 4-ball XFBGA/DSBGA (4-DSBGA) package, the TPS22914CYFPT is a surface-mount part with a tiny footprint — expect to use a microscope for placement and a hot-air station for rework; this is not a hand-solder part.
