Dual-Slot PCMCIA/CardBus Power Controller Features Backward Compatible with G570 Fully Integrated VCC and Vpp Switching for Dual Slot PC Card TM Interface 3-Lead Serial Interface Compatible With CardBus TM Controllers 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 Short Circuit and Thermal Protection 30 Pin SSOP Compatible With 3.3V, 5V and 12V PC Cards Low RDS(on) (180-mΩ 5V VCC Switch; 130 m Ω 3.3V V CC Switch) Break-Before-Make Switching Internal power-On Reset Standby mode: 60mA current limit (TYP) Application Notebook PC Electronic Dictionary POS 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. 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 VCC and VPP (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.
