Description
The G571 PC Card power-interface switch provides an
integrated power-management solution for a single 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. The circuit allows the distribution of 3.3V, 5V,
and/or 12V card power, and is compatible with many
PCMCIA controllers. The current-limiting feature
eliminates the need for fuses, which reduces compo-
nent count and improves reliability. Current-limit re-
porting can help the user isolate a system fault to the
PC Card.
The G571 features a 3.3V low voltage mode that al-
lows for 3.3V switching without the need for 5V. Bias
power can be derived from either the 3.3V or 5V inputs.
This facilitates low-power system designs such as
sleep mode and pager mode where only 3.3V is
available.
End equipment for the G571 includes notebook com-
puters, desktop computers, personal digital assistants
(PDAs), digital cameras and bar-code scanners.

... The AVPP out- puts limit from 120mA to 400mA, typically around 200mA. The protection circuitry acts by linearly limiting the current passing through the switch rather than ini- tiating a full shutdown of the supply. Shutdown occurs only during thermal limiting. 8 G571 / R DS(on) TEL: 886-3-5788833 http://www.gmt.com.tw ...

... High switching currents can produce large negative voltage transients, which forward biases sub- strate diodes, resulting in unpredictable performance.
