Description

The G5794P11U is an IC Chip in the product category of Electronic Components. It is a PC Card power-interface switch that provides a comprehensive power-management solution for a single PC Card. This integrated circuit combines discrete power MOSFETs, a logic section, current limiting, and thermal protection for PC Card control. It allows for the distribution of 3.3V, 5V, and/or 12V card power and is compatible with various PCMCIA controllers. The current-limiting feature eliminates the need for fuses, reducing component count and improving reliability. Additionally, the G5794P11U features a 3.3V low voltage mode that enables 3.3V switching without the need for 5V, making it suitable for low-power system designs such as sleep mode and pager mode. Common applications for this component include notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras, and bar-code scanners.
