Single-Channel CardBus and PCMCIA VCC/VPP
Power-Switching Network
_______________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.
