Available in 8-Pin and 16-Pin SO Packages
The LTC
®
1470 switches the V
CC
pins of a Personal Com-
puter Memory Card International Association (PCMCIA)
card slot between three operating states: OFF, 3.3V and
5V. Two low R
DS(ON)
N-channel power MOSFETs are
driven by a built-in charge pump which generates a
voltage higher than the supply voltage to fully enhance
each switch when selected by the input control logic.
The LTC1470 inputs are compatible with industry stan-
dard PCMCIA controllers. A built-in XOR ensures that both
switches are never on at the same time. This function also
makes the LTC1470 compatible with both active-low and
active-high controllers (see Applications Information sec-
tion). The switch rise times are controlled to eliminate
power supply glitching.
The LTC1470 features built-in SafeSlot
TM
current limit and
thermal shutdown. The output is limited to 1A during short
circuit to ground but 2A of peak operating current is
allowed.
The LTC1471 is a dual version of the LTC1470 and is
available in a 16-pin SO package.
