________________General Desc ription
The MAX1601/MAX1604 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 switches are programmed to high-Z or
GND states over the serial interface, unlike other solu-
tions that may require a separate shutdown-control
input.
Other key features include guaranteed specifications for
output current limit level, and guaranteed specifications
for output rise/fall times (in compliance with PCMCIA
specifications). Reliability is enhanced by thermal-over-
load protection, accurate current limiting, an overcur-
rent-fault flag output, undervoltage lockout, and extra
ESD protection at the VCC/VPP outputs. The SMBus ser-
ial interface is flexible, and can tolerate logic input levels
in excess of the positive supply rail.
The MAX1604 and MAX1601 are identical, except
for the MAX1604’s VY switch, which has roughly three-
times the on-resistance (typically 140m
).The
MAX1601/MAX1604 fit two complete CardBus/PCMCIA
switches into a space-saving, narrow (0.2in. or 5mm
wide) SSOP package.
