Dual-Slot, PCMCIA Analog Power Controller

All versions are No Longer Available.

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/high-impedance power outputs for flash V_PP 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 edge-triggered 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 V_PP valid indicators, and the digital input registers.
