Description
The G574 PC Card power-interface switch provides an
integrated power-management solution for two PC Cards.
All of the discrete power MOSFETs, a logic section, cur-
rent limiting, and thermal protection for PC Card control
are combined on a single integrated circuit (IC). The cir-
cuit 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 re-
duces component count and improves reliability.
The G574 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 G574 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 V
CC
and V
PP
(flash-memory programming voltage) outputs, which
discharges residual card voltage.
This device also has the ability to program the xVpp
outputs independent of the xVCC outputs. A standby
mode that changes all output-current limits to 50mA
(typical) has been incorporated.
End equipment for the G574 includes notebook com-
puters, desktop computers, personal digital assistants
(PDAs), digital cameras and bar-code scanners
.
The G574 is backward-compatible with the G570.
