MIC2566
Single-Slot PC Card/CardBus Power Controller
Preliminary
General Description
The MIC2566 single-slot PC Card / CardBus power controller
is a V
CC
and V
PP
power switch matrix that supports 3.3V and
5V PC Card (PCMCIA) slot power supply pins.
The MIC2566 can switch PC Card slot V
CC
voltages between
0V (ground), 3.3V and 5.0V and V
PP
voltages between 0V
(ground), 3.3V, 5V, or high impedance at output currents of
up to 1A for V
CC
and 200mA for V
PP
. The MIC2566 features
well-controlled voltage rise and fall times. Each MIC2566
output voltage is switched by two digital inputs, typically
controlled from a separate PC Card logic controller.
The MIC2566 is designed for efficient operation. In standby
(sleep) mode the device draws very little quiescent current,
typically only 0.3µA. The power controller includes thermal
shutdown and protects itself and its PC Card ports with
current limiting. Full cross-conduction lockout protects the
system power supplies.
The MIC2566 is available in 14-pin SOP and TSSOP
packages.
