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 cir-
cuit (IC). The circuit allows the distribution of 3.3V, 5V,
and/or 12V card power by means of the Serial inter-
face. The current-limiting feature eliminates the need
for fuses, which reduces component count and im-
proves 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 com-
puters, desktop computers, personal digital assistants
(PDAs), digital cameras and bar-code scanners.
