Architecture for switching power source to load in a battery powered system

摘要

The present invention comprises a combination of a new circuit topology utilizing microcontroller (202) and a modified logic control circuit which enables the replacement of a Schottky diode, commonly used in series with AC adapter, by a MOS transistor switch (212) to implement airline mode operation of a system, with the added benefits of more efficient power dissipation and minimization of sparking or arcing at the power input terminal.
