The MAX1602 DC power-switching IC contains a net-

work 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,

32-bit CardBus applications is supported in two ways:

low-resistance 3.3V switches allow high 3.3V load cur-

rents (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 con-

sumption is automatically reduced to 11µA max when

the outputs are high-Z or GND.

Other key features include guaranteed specifications

for output current limit level, and guaranteed specifi-

cations for output rise/fall times (in compliance with

PCMCIA specifications). Reliability is enhanced by

thermal-overload protection, accurate current limiting,

an overcurrent-fault flag output, and undervoltage lock-

outs. The CMOS/TTL-logic interface is flexible, and can

tolerate logic input levels in excess of the positive sup-

ply rail.

The MAX1602 fits a complete CardBus/PCMCIA switch

into a space-saving, 16-pin QSOP package.
