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
VCC and VPP. The MIC2563A switches between the three V
voltages (0V, 3.3V and 5.0V) and the VPP voltages (OFF, 0V,

3.3V, 5V, or 12.0V) required by PC Cards. The MIC2563A
switches voltages from the system power supply to VCC and
VPP. Output voltage is selected by two digital inputs each and
output current ranges up to 1A for VCC and 250mA for VPP.

The MIC2563A provides power management capability con­trolled by the PC Card logic controller. Voltage rise and fall
times are well controlled. Medium current VPP and high
current VCC 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 cross­conduction lockout protects the system power supplies.

The MIC2563A is an improved version of the MIC2563,
offering lower ON-resistances and a VCC pulldown clamp in
the OFF mode. It is available in a 28-pin SSOP.
