MIC2563A
Dual-Slot PCMCIA/CardBus Power Controller
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 sup-
ply 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 dur-
ing switching operations.
The MIC2563A is an improved version of the MIC2563,
offering lower on-resistances and a V
CC
pull-down clamp in
the OFF mode. It is available in a standard 28-pin SSOP, as
well as an environmentally friendly (lead-free) 28-pin SSOP.
All support documentation can be found on Micrel’s web
site at www.micrel.com.
