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 0.3
μ
A. 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.
