_______________General Description
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: There are no parasitic diodes between any of these pins, so there are no power-up sequencing restrictions (for example,
logic input signals can be applied even if all of the supply voltage inputs are grounded).
Note 2: VCC and VPP outputs are internally current limited. See the
