XR46004-Q

AEC-Q100 Qualified 600mA High Voltage Adjustable Current Regulator with Enable Control

Description

The XR46004-Q is a high voltage, low dropout current regulator of output current up to 600mA in maximum. Users can adjust the output current from 100mA to 600mA through an external resistor, RSET, which gives users flexibility in controlling the light intensity of the LEDs. Further, the LED brightness is adjustable via the OE pin with a Pulse Width Modulation signal.
 
The thermal protection function protects the IC from over temperature damage. Also, the exposed thermal pad enhances the package power dissipation.

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.
