The MAX1600/MAX1603 DC power-switching ICs con-

tain 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, soft-

switching action, and compliance with PCMCIA specifi-

cations 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 nor-

mally, even if the +5V and +12V supplies are discon-

nected 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 control logic inputs are programmed to

high-Z or GND states, unlike other solutions that may

require a separate shutdown-control input.

Other key features include guaranteed specifications

for output current limit level, and guaranteed specifica-

tions 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-

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

tolerate logic input levels in excess of the positive sup-

ply rail.

The MAX1600 and MAX1603 are identical, except for

the MAX1603’s VY switch on-resistance (typically

140mΩ). The MAX1600/MAX1603 fit two complete

CardBus/ PCMCIA switches into a space-saving, narrow

(0.2in. or 5mm wide) SSOP package.
