General Description
The MIC2558 Dual V
PP
Matrix switches the four voltages
required by PCMCIA (Personal Computer Memory Card
International Association) card V
PP1
and V
PP2
Pins. The
MIC2558 provides selectable 0V, 3.3V, 5.0V, or 12.0V (
±
5%)
from the system power supply to V
PP1
and V
PP2
. Output
voltage is selected by two digital inputs per V
PP
pin. Output
current ranges up to 120mA. Four output states, V
PP
, V
CC
,
high impedance, and active logic low are available, and V
PP1
is independent of V
PP2
. An auxiliary control input determines
whether the high impedance (open) state or low logic state is
asserted.
In standby mode or full operation, the device draws very little
quiescent current, typically less than 1
μ
A.
The MIC2558 is available in a 14-pin SOIC and a 14-pin
plastic DIP.
