POWER SWITCH CIRCUITS
O2Micro's PC Card power interface switches provide an integrated power management solution for a single PC Card. ExpressSwitch™ (part #OZ27C10), the latest addition to the Power Switch family, is an integrated single-chip power switching solution for an ExpressCard™ (a trademark of PCMCIA) slot. They are used in conjunction with a data output CardBus controller to control and distribute VCC and VPP voltages to PC Card slot(s). They are "Designed for Microsoft Windows" logo certified, including the CardBus and Zoomed Video (ZV) options.
