A dual-slot power-interface switch for PCMCIA controllers using a novel bi-directional switching concept, built in a 1 /spl mu/m BiCMOS/DMOS power process

PCMCIA cards are used to add a variety of features to portable computers-modems, LANs, GPS, etc. Some means of switching power to the inserted PCMCIA card is required: this paper describes the design and process technology for a second-generation, single-chip, dual-slot PCMCIA power interface switch.
