  • Electronic apparatuses and electronic systems using the same for providing supply voltage to external devices
    Patent number: 8334720
    Abstract: An electronic apparatus for providing supply voltage to a first external device with a predetermined pin assignment specification is provided. The electronic apparatus includes a connection interface and a voltage supplier. The connection interface includes a first pin and a second pin. The voltage supplier provides a detection voltage signal to the first pin and determines whether to provide the supply voltage according to whether the second pin is at a first level in response to the detection voltage signal. When the second pin is at the first level in response to the detection voltage signal, the voltage supplier provides the supply voltage to the first pin.
