In the case that PD negotiation fails, there is sometimes a fallback “safe power” rail. These might typically supply 5V @ 900mA, or similar. The TPS25730x does not include this featureincludes this feature - however, its open drain output pins do not respond to regular USB power events (only those matching the USB-PD protocol).
The TPS25730S recommends the https://www.digikey.ca/en/products/detail/texas-instruments/CSD87501L/5126233, while the TPS25730D comes with an integrated gate in the package. Given the small price delta between the S and D models, the TPS25730D is a practical choice, and very simply concludes our FET selection.
