Description

The G570 PC Card power-interface switch provides an integrated power-management solution for two 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 (IC). The circuit allows the distribution of 3.3V, 5V, and/or 12V card power by means of the Serial interface. The current-limiting feature eliminates the need for fuses, which reduces component count and improves reliability.
