Overview
Global Mixed-mode Technology Inc.
G570 Dual-Slot PCMCIA/CardBus Power Controller Features „Fully Integrated VCC and Vpp Switching for Dual 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.
The G570 features a 3.
3V low voltage mode that allows for 3.
3V switching without the need for 5V supply.
This facilitates low power system designs such as sleep mode and pager mode where only 3.
3V is available.
The G570 incorporates a reset function, selectable by one of two inputs, to help alleviate system errors.
The reset function enables PC card initialization concurrent with host platform initialization, allowing a system reset.
Reset is accomplished by grounding the VCC and VPP (flash-memory programming voltage) outputs, which discharges residual card voltage.
End equipment for the G570 includes notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras and bar-code scanners.
