LTC1472
Protected PCMCIA V
CC
and
VPP Switching Matrix
The LTC
1472 switching matrix routes power to both the
V
CC
and VPP power supply pins of the PCMCIA compatible
card socket. The V
CC
output of the LTC1472 is switched
between three operating states: OFF, 3.3V, and 5V. The
VPP output is switched between four operating states: 0V,
V
CC
, 12V, and Hi-Z. The output voltages are selected by
two sets of digital inputs which are compatible with
industry standard PC Card controllers (see Truth Tables).
The V
CC
output of the LTC1472 can supply up to 1A of
current and the VPP output up to 120mA. Both switches
have built-in SafeSlot
TM
current limiting and thermal shut-
down to protect the card, socket and power supply against
accidental short-circuit conditions.
The LTC1472 is designed to conserve power by automati-
cally dropping to 1
μ
A standby current when the two
outputs are switched OFF. A shutdown pin is provided
which holds the external 12V regulator in standby mode
except when required for VPP power.
The LTC1472 is available in 16-pin SO.
