  • System and method for brownout protection of a FET based battery switch
    Patent number: 7336005
    Abstract: A switching circuit operative to switch between a first and second power source to an output is disclosed. The circuit comprises a MOSFET switch electrically connected to the first and second power sources and operative to provide power from either one of the power sources to the output. The circuit includes a RC network electrically connected to a gate of the MOSFET switch. The RC network is operative to delay switching between the first and second power sources such that the second power source has the opportunity to fully ramp-up in order to provide continuous power to the output. Accordingly, the second power source can fully provide power to the output when the power is switched from the first power source to the second power source.
    Type: Grant
