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.
