ADM2587E Maximum Operating Temperature

Question asked by ellisplace on Jan 6, 2012

Hello

 

I use the ADM2587E RS485 isoPower interface in my product, I recently changed interface to reduce the need for a seperate power source to the isolated comms side.

 

After a variety of temperature rise tests I found that the part kicks off quite a bit of heat. I currently measure 20'C above ambient. This unfortunately takes us about 9'C over the maximum operating temperature when our device is at its specified maximum operating temperature of 75'C.

 

Are there any higher temp. rated products, or is there any way to reduce the device temperature by modifying the PCB?

 

Thank you for any assistance you can offer

 

Kind Regards
