MIC2563A
Dual Slot PCMCIA/CardBus Power Controller
Preliminary Information
General Description
The MIC2563A Dual Slot PCMCIA (Personal Computer
Memory Card International Association) and CardBus Power
Controller handles all PC Card slot power supply pins, both
V
CC
and V
PP
. The MIC2563A switches between the three V
CC
voltages (0V, 3.3V and 5.0V) and the V
PP
voltages (OFF, 0V,
3.3V, 5V, or 12.0V) required by PC Cards. The MIC2563A
switches voltages from the system power supply to V
CC
and
V
PP
. Output voltage is selected by two digital inputs each and
output current ranges up to 1A for V
CC
and 250mA for V
PP
.
The MIC2563A provides power management capability con-
trolled by the PC Card logic controller. Voltage rise and fall
times are well controlled. Medium current V
PP
and high
current V
CC
output switches are self-biasing:
no +12V supply
is required for 3.3V or 5V output.
The MIC2563A is designed for efficient operation. In standby
(sleep) mode the device draws very little quiescent current,
typically 0.3µA. The device and PCMCIA port is protected by
current limiting and overtemperature shutdown. Full cross-
conduction lockout protects the system power supplies.
The MIC2563A is an improved version of the MIC2563,
offering lower ON-resistances and a V
CC
pulldown clamp in
the OFF mode. It is available in a 28-pin SSOP.

The MIC2563A uses V

CC3 IN
and V
CC5IN
. See Applica-
tions Information for further details.
V
PP IN

V
PP IN
must be either high impedance or greater than or approximately equal to the highest voltage V

example, if both 3.3V and 5V are connected to the MIC2563A, V

must be either 5V, 12V, or high impedance.
