Active production — what this means for your BOM
2 A output, 37 mOhm — sizing the load switch
Rated for 2 A continuous output current, the TPS22914BYFPR can power a modest peripheral rail, sensor cluster, or sub-regulator input. The 37 mOhm typical Rds(on) at 5 V bias means a voltage drop of roughly 74 mV at full load — negligible for most 3.3 V or 5 V rails, but worth checking against the downstream supply tolerance. The load voltage range spans 1.05 V to 5.5 V, covering common logic and I/O voltages. No external Vcc supply is required — the switch is self-biased from the load voltage.
Slew-rate control and thermal design
The slew-rate controlled turn-on limits inrush current when switching into a capacitive load, which prevents upstream supply droop and reduces EMI. This is a practical feature for power-sequencing or hot-swap applications where a sudden current surge could reset a shared rail.
Package and footprint — what to expect
Housed in a 4-bump DSBGA package, the TPS22914BYFPR requires a fine-pitch layout with a solder-mask-defined pad. The supplier device package is 4-DSBGA. Surface-mount assembly is standard, but the small bump size means a clean stencil aperture and reflow profile are critical to avoid head-in-pillow defects.
