Reserve Power Circuit for LS1012A Design

Hello, I am designing a small board with the LS1012A ARM Processor. The board will likely consume about 16W of power. I will need to design a reserve power circuit to supply power to the board for a short amount of time. Does NXP have any devices that I could use to monitor the input power and switch over to some supercaps to provide a short time of power to the board, say 2 seconds or so, enough time for the Processor to finish what it was doing and go through the power down sequence of the Linux OS.

 

Thanks,

Joe
