MAX780

19-0125; Rev. 1; 8/93 Dual-Slot PCMCIA Analog Power Controller _______________General Description The MAX780A provides the power switching and status signals necessary to control two Personal Computer Memory Card International Association (PCMCIA) Release 2.0 card slots. The MAX780A, used in conjunction with a PC Card Interface Digital Controller, forms a complete, minimum component count PCMCIA interface for palmtop and notebook computers. The MAX780A incorporates two 0V/+5V/+12V/highimpedance power outputs for flash VPP programming, level shifters for power MOSFET control of two separate +3.3V/+5V supplies, and two V PP power-ready status signals. The MAX780A may be directly connected to the control outputs from a PCMCIA digital controller, or may be configured to use internal edgetriggered registers for connection to the CPU data bus. The MAX780B has all the features of the MAX780A but omits the reference and V PP valid indicators. The MAX780C has all the features of the MAX780A but omits the registers for the digital inputs. The MAX780D omits the reference, the VPP valid indicators, and the digital input registers. ___________________________Features o SSOP Circuit Fits in 0.09in2 o Smallest Complete Analog Controller for Two PCMCIA (Release 2.0/JEIDA 4.1) PC Card Sockets o Dual VCC Contols and VPP Outputs o Logic-Compatible with Industry-Standard PCMCIA Digital Controllers: Intel 82365SL_DF Fujitsu MB86301 Chips and Technology F8680 Cirrus Logic CL-PD6720 o 0V/+5V/+12V...
