Maxim Integrated MAX1604
The MAX1604 and MAX1601 are identical, except for the MAX1604’s VY switch, which has roughly threetimes the on-resistance (typically 140m Ω ).The MAX1601/MAX1604 fit two complete CardBus/PCMCIA switches into a space-saving, narrow (0.2in.- Min Voltage : 2.2V
- Max Voltage : 28V

DESCRIPTION
The MAX1601/MAX1604 DC 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. Key features include ultra-low-resistance switches, small packaging, softswitching action, and compliance with PCMCIA specifications for 3V/5V switching. 3.3V-only power switching for fast, 32-bit CardBus applications is supported in two ways: stiff, 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. Also, power consumption is automatically reduced to 10µA max when the switches are programmed to high-Z or GND states over the serial interface, unlike other solutions that may require a separate shutdown-control input.
