This circuit shows a low-loss way to implement a glitch-free battery backup for a memory or similar circuit. The feedback string is arranged so that one LT1020 does not conduct under line-powered conditions. When the line goes down, the line LT1020 begins to go off, which allows the battery-driven LT1020 to turn on and maintain the load.
