♦ Supports Two CardBus Sockets

The MAX1601/MAX1604 DC power-switching ICs con-

tain a network of low-resistance MOSFET switches that

d e live r s e le c ta b le VCC a nd VPP volta g e s 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.

♦ 1A, 0.08Ω Max VY VCC Switch (MAX1601 only)

♦ Soft Switching for Low Inrush Surge Current

♦ Overcurrent Protection

♦ Overcurrent/Thermal-Fault Flag Output

♦ Thermal Shutdown at T_j= +150°C

♦ Independent Internal Charge Pumps

♦ Break-Before-Make Switching Action

♦ 10µA Max Standby Supply Current

Specifications

♦ Super-Small, 28-Pin SSOP Package

(0.2in. or 5mm wide)

♦ System Management Bus (SMBus) Serial

Interface

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.
