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 Ca rd hos t s oc ke t. Ke y fe a ture s inc lud e 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

turne d off to c ons e rve p owe r. The inte rna l c ha rg e

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.

♦ Supports a Single PC Card/CardBus Socket

♦ 1A, 0.25Ω Max 3.3V VCC Switch

1A, 0.25Ω Max 5V VCC Switch

♦ Soft Switching for Low Inrush Surge Current

♦ Overcurrent Protection

♦ Overcurrent/Thermal-Fault Flag Output

♦ Thermal Shutdown at T = +150°C

♦ Independent Internal Charge Pumps

♦ Break-Before-Make Switching Action

♦ 11µA Max Standby Supply Current

♦ 5V and 12V Not Required for Low-R

DS(ON)

3.3V Switching

♦ Complies with PCMCIA 3V/5V Switching

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.
