G574

Dual-Slot PCMCIA/CardBus Power Controller

Features

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 sec-

tion, 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 reliabil-

ity.

Backward Compatible with G570

Fully Integrated V_CCand V_ppSwitching for Dual

Slot PC Card^TMInterface

3-Lead Serial Interface Compatible With

CardBus^TMControllers

3.3V Low Voltage Mode

Meets PC Card Standards

RESET for System Initialization of PC Cards

12V Supply Can Be Disabled Except During

12V Flash Programming

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_CCand V_PP

(flash-memory programming voltage) outputs, which

discharges residual card voltage.

Short Circuit and Thermal Protection

30 Pin SSOP

Compatible With 3.3V, 5V and 12V PC Cards

Low R_DS(on)(180-mΩ 5V V_CCSwitch;

130 mΩ 3.3V V_CCSwitch)

Break-Before-Make Switching

Internal power-On Reset

Standby mode: 60mA current limit (TYP)

Application

Notebook PC

Electronic Dictionary

POS

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.
