The MAX1602EEE+ is a single-channel CardBus and PCMCIA VCC/VPP power switching network in 16 pin QSOP package. The DC power switching IC contains a network of low-resistance MOSFET switches that deliver selectable VCC and VPP voltages to a single CardBus or PC Card host socket. Key features include low resistance switches, small packaging, soft-switching action and compliance with PCMCIA specifications for 3V/5V switching. 3.3V-only power switching for fast, 32bit CardBus applications is supported in two ways low-resistance 3.3V switches allow high 3.3V load currents (up to 1A) and completely independent internal charge pumps let the 3.3V switch operate normally, even if the +5V and +12V supplies are disconnected or turned off to conserve power. The internal charge pumps are regulating types that draw reduced input current when the VCC switches are static. Power consumption is automatically reduced to 11μA max when the outputs are high-Z or GND.
