... Dual-Channel CardBus and PCMCIA Power Switches with SMBus™ Serial Interface _______________Detailed Description The MAX1601/MAX1604 power-switching ICs contain a network of low-resistance MOSFET switches that deliver selectable VCC and VPP voltages to two Cardbus or PC Card host sockets. The MAX1601/MAX1604 differ only in the VY switch on-resistance. Figure 1 is the detailed block diagram ...

... Dual-Channel CardBus and PCMCIA Power Switches with SMBus™ Serial Interface ______SMBus™ Interface Operation The SMBus serial interface is a two-wire interface with multi-mastering capability, intended to control low- speed peripheral devices in low-power portable equip- ment applications. SMBus is similar to I AccessBus, but has slightly different logic threshold voltage levels, different fixed addresses, and a sus- pend-mode register capability ...
