  • Method of overcurrent protection for multi-slot flash memory card reader
    Patent number: 7293710
    Abstract: A method of overcurrent protection for multi-slot flash memory card reader mainly includes integrating overcurrent protection circuit and power-supply circuit for the multiple slots of the card reader into one single control chip; and, when the overcurrent protection circuit detects an overcurrent at a particular slot, cutting off power supply to that particular slot of the card reader and enabling an overcurrent state register, so that a signal is provided to firmware in the control chip to display an icon of the card reader on a computer as a state indicating an abnormal condition. Whereby, the card reader and a flash memory card inserted therein, or other apparatus connected thereto would not be damaged when an overcurrent occurs, and a user may clearly know the exact point on the card reader where the overcurrent occurs.
