Description

The G576 PC Card power-interface switch provides an integrated power-management solution for dual-slot PC Cards. All of the discrete power MOSFETs, a logic section, current limiting, and thermal protection for PC Card control are combined on a single integrated circuit. The circuit allows the distribution of 3.3V, 5V, and/or 12V card power, and is compatible with many PCMCIA controllers. The current-limiting feature eliminates the need for fuses, which reduces component count and improves reliability. Current-limit reporting can help the user isolate a system fault to the PC Card.
