APPLICATION NOTE 1195
Maximize Battery Life and Minimize Replacements

Abstract: The MAX6326 microprocessor supervisor is used in an application to provide a battery switchover
circuit when the wall adapter is disconnected. The reset output drives an external MOSFET that is used as a
switch. This switchover circuit also debounces the wall-source output during switchover.


Battery-powered portable and handheld devices with plug-in wall adapters must switch automatically between
the battery and the wall source when the AC adapter is connected. A common way to do this is with a diode-OR
connecti……
