Product details

What this USB power switch does on your board

The Texas Instruments TPS2530DBVR is a single-channel high-side N-channel USB power switch in a SOT-23-5 package. It handles a 500 mA continuous output from a 2.7 V to 5.5 V load supply, with a typical on-resistance of 97 mOhm.

Fault protection — the failure signatures a repair bench looks for

This part packs four fault protections: fixed current limiting, over-temperature shutdown, reverse-current blocking, and undervoltage lockout (UVLO).

Temperature grade and where it fits

That means no last-time-buy scramble, no forced redesign for the foreseeable future.

Frequently asked questions

What are the fault protections of TPS2530DBVR?

The TPS2530DBVR includes current limiting (fixed), over-temperature shutdown, reverse-current blocking, and undervoltage lockout (UVLO). These protections cover the common failure modes on USB power rails — shorted load, thermal runaway, back-feed during sequencing, and brownout conditions.

What is the maximum current for TPS2530DBVR?

The maximum continuous output current is 500 mA. The current limit is fixed internally, so the switch will fold back above that threshold. For loads exceeding 500 mA, look at the TPS2530D variant or a higher-current USB switch in the same family.

Is TPS2530DBVR compatible with TPS2530D?

The TPS2530DBVR and TPS2530D share the same base design (TPS2530) and identical fault protection and control logic. The main difference is the package: the DBVR is in SOT-23-5, while the TPS2530D typically comes in an SOIC-8. Check the pinout and footprint before substituting — they are not drop-in compatible without a board layout change.
