Current Limited Load Switches (USB PCMCIA)
Current Limited Load Switches are designed for high-side power switching applications to cover a wide range of port protection applications for USB, PCMCIA (PC cards), and IEEE1394 (Firewire) ports in desktop and notebook computers. Port protection switches provide inrush current limiting, short-circuit and over-temperature protection, in addition to input control level shifting and fault flags. Designers can select different current limit options from preset thresholds to user-adjustable limits using just one external resistor. Single, dual, and quad switches are available to fulfill a wide array of application requirements.
