13.3 mOhm Rds(on) — the conduction loss floor
That Rds(on) figure sets the conduction loss: at 3 A, expect about 120 mW dissipation in the die — well within the 6-DSBGA's thermal budget for most board layouts, but the tiny 1.39 x 0.89 mm package means the copper pad area under the part is what pulls the heat out.
The on/off interface is non-inverting, and the part includes reverse current protection, a useful safeguard when sequencing multiple rails or using a backup battery.
Industrial temp grade and slew rate control
The slew-rate-controlled turn-on limits inrush current, which prevents the input supply from drooping when a capacitive load is switched in — a common headache in distributed power systems.
The base product number is TPS22963, which covers the family of load switches in this DSBGA footprint.
