Dual-Slot PCMCIA/CardBus Power Controller Features 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 28 Pin and 30 Pin SSOP Compatible With 3.3V, 5V and 12V PC Cards Low RDS(on) (225-mΩ Ω Ω Ω 5V V CC Switch; 200 m Ω Ω Ω Ω 3.3V V CC Switch) Break-Before-Make Switching Internal power-On Reset Application Notebook PC Electronic Dictionary Personal Digital Assistance Digital still Camera Description The G570 PC Card power-interface switch provides an integrated power-management solution for two 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 (IC). The circuit allows the distribution of 3.3V, 5V, and/or 12V card power by means of the Serial inter- face. The current-limiting feature eliminates the need for fuses, which reduces component count and im- proves reliability. The G570 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 G570 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. End equipment for the G570 includes notebook com- puters, desktop computers, personal digital assistants (PDAs), digital cameras and bar-code scanners . Ordering Information PART NUMBER TEMP.
