Dear All,

I have seached through 8052 - SEARCH and found many links for dual power supply connections.

One of them suggested for
Using RELAY - By Michal -
Subject -- Dual Vcc Configuration?

Even I found one solution for using two diodes as we normally use for battery back up.

But this time I have one 5V/3A supply from SMPS and another 6V/10Ah battery and for this 5V/3A I am suppose to give backup using this battery for the times when mains supply is broken.

There was a link found for MAX1773.

Kindly help.
