200 mOhm Rds(on) — the 25 °C headline that needs derating
Texas Instruments TPS22916CLYFPR is a single-channel, high-side P-channel load switch in a 4-DSBGA package. The 200 mOhm Rds(on) typical is specified at 25 °C — at 85 °C junction, that figure roughly doubles, so budget around 400 mOhm for conduction loss in a warm enclosure. The 2 A continuous output rating at 25 °C drops with temperature; stay inside the SOA for your ambient.
Slew-rate control and reverse-current protection
The slew-rate controlled turn-on limits inrush current into capacitive loads, reducing supply droop on the rail. Fault protection includes reverse-current blocking — if the output voltage exceeds the input, the switch turns off, preventing back-feed into the source. Input supply range is 1 V to 5.5 V, load range is 0 V to 5.5 V, covering 1.8 V, 2.5 V, 3.3 V, and 5 V rails common in portable and embedded systems.
Active production — order against BOM quantity
The base product number TPS22916 covers multiple output-voltage and package variants; the CLYFPR suffix selects the 4-DSBGA package with tape-and-reel or cut-tape delivery.
