3.0V to 5.5V USB Power Control Switch
Data Sheet


The SP2525A device is an integrated high-side power switch ideal for self-powered and buspowered Universal Serial Bus (USB) applications.
The high-side switches are MOSFETs with 70mΩ RDS(ON), which meets USB voltage drop requirements for maximum transmission wire
length. Multi-purpose open-drain fault flag output indicates over-current limiting, thermal shutdown, or undervoltage lockout for each channel. Output current is typically limited to 0.85A below the 5A safety requirement, and the thermal shutdown function shuts the switch off to prevent damage under overcurrent conditions. Guaranteed minimum output rise time limits inrush current during hot plug-in, minimizing EMI and preventing the voltage at the upstream port from dropping excessively.


  • 3.0V to 5.5V input voltage range
  • 500mA continuous load current per channel
  • 2.6V undervoltage lockout
  • 1.25A short-circuit current limit
  • 100mΩ maximum on-resistance
  • 75µA on-state supply current
  • 1µA shutdown current
  • Output can be forced higher than input
  • (off-state)
  • Thermal shutdown
  • Slow turn on and fast turn off
  • Active-high version: SP2525A-1
  • Active-low version: SP2525A-2

Frequently Asked Questions

The best way to determine this is to go to maxlinear.com and type the part into the search function. At or near the top of the results you should see something that looks like:

In this example, we looked for XRA1201. Click on part number header or on the link at the bottom of the result.  This brings you to the product page. For example:


Click on Parts & Purchasing, highlighted with the blue arrow above. The screen changes to:


Notice the status column and the “Show obsolete parts” link.  A legend tells you the definition of the different statuses. Click on the “Show obsolete parts” link to see EOL or OBS part numbers along with the Active part numbers, the legend still present:


Another method to find out if a part is OBS or EOL is to click on SUPPORT at the top:


And then Product Change Notifications:


Type the part into the search, and click on one of the part numbers from the drop down menu. Then you can look for the Product Discontinuation Notice, which generally is at the top of the list, for example:


If you see this, it tells you that this particular orderable part has been discontinued and when the last order date is, or was. If you click on the file, then you can view the notice we sent about this if you purchased the part in the recent past. It may also advise of a replacement part. When an orderable part first becomes discontinued, Product Discontinuation Notices are sent are sent to those who have purchased the parts in the recent past, if purchased directly, with a dated opportunity to place a last order.
