General Description
The MIC2562A PCMCIA (Personal Computer Memory Card
International Association) and CardBus power controller
handles all PC Card slot power supply pins, both V
V
ages (0V, 3.3V and 5.0V) and the V
3.3V, 5V or 12.0V) required by PC Cards. The MIC2562A
switches voltages from the system power supply to V
V
output current ranges up to 1A for V
The MIC2562A provides power management capability con-
trolled by the PC Card logic controller. Voltage rise and fall
times are well controlled. Medium current V
current V
ply is required for 3.3V or 5V output.
The MIC2562A is designed for efficient operation. In standby
(sleep) mode, the device draws very little quiescent current,
typically 0.3 A. The device and PCMCIA port is protected by
current limiting and overtemperature shutdown. Full cross-
conduction lockout protects the system power supply during
switching operations.
The MIC2562A is an improved version of the MIC2562,
offering lower on-resistance and a V
the OFF mode. It is available in a 14-pin (0.150") SOIC, and
the -1 logic option is also available in 16-pin TSSOP
All support documentation can be found on Micrel’s web
