General Description

MIC2563A
Dual-Slot PCMCIA/CardBus Power Controller
Features
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 0.3 μ A. The device and PCMCIA port is protected by
current limiting and overtemperature shutdown. Full cross-
conduction lockout protects the system power supplies dur-
ing switching operations.
? UL recognized, file #179633
Applications
? Dual-slot PC card power supply pin voltage switch
? CardBus slot power supply control
? Data collection systems
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.
