  • Power supply apparatus of mobile terminal
    Patent number: 7457645
    Abstract: A power supply apparatus supplies power to a mobile terminal through a USB (Universal Serial Bus). This power drives the terminal to perform USB communication functions even when an external power source of the terminal is disconnected or non-operational. Through this control technique, USB communications can be unlimitedly performed only with the USB cable regardless of capacity of the external power source. A problem that the terminal is turned off due to power shortage during data transmission and reception can therefore be prevented.
