XRP2528

Dual-Channel Adjustable Current Power Distribution Switch

Description

The XRP2528 is a dual-channel integrated high-side power distribution switch with individual channel enables, individual channel fault flags and precise programmable current limit thresholds. A wide 1.75V to 5.5V input voltage range allows for operations from industry standard 1.8V, 3.3V and 5V power rails.

Current limit thresholds can be programmed accurately via external resistors. A simple setting optimizes the XRP2527 for use in USB 2.0 or 3.0 compliant VBUS power distribution architectures. The power-switch rise and fall times are controlled to minimize current surges during turn on/off.

Built-in overcurrent, undervoltage lockout (UVLO), reverse current and over temperature protections insure safe operations under abnormal operating conditions.

Frequently Asked Questions

The best way to determine this is to go to exar.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. When you hover over it, it will turn grey and you can click anywhere in the grey box. This brings you to the product page. For example:

 
 

Click on Parts & Purchasing, highlighted in yellow 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:

 
 

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

 

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.
