MIC2561
PCMCIA Card Socket V
CC
and V
PP
Switching Matrix
Final Information
General Description
The MIC2561 V
CC
& V
PP
Matrix controls PCMCIA (Personal
Computer Memory Card International Association) memory
card power supply pins, both V
CC
and V
PP
. The MIC2561
switches voltages from the system power supply to V
CC
and
V
PP
. The MIC2561 switches between the three V
CC
voltages
(OFF, 3.3V and 5.0V) and the V
PP
voltages (OFF, 0V, 3.3V,
5V, or 12.0V) required by PCMCIA cards. Output voltage is
selected by two digital inputs for each output and output
current ranges up to 750mA for V
CC
and 200mA for V
PP
. For
higher V
CC
output current, please refer to the full-perfor-
mance MIC2560.
The MIC2561 provides power management capability under
the control of the PC Card controller and features overcurrent
and thermal protection of the power outputs, zero current
“sleep” mode, suspend mode, low power dynamic mode, and
ON/OFF control of the PCMCIA socket power.
The MIC2561 is designed for efficient operation. In standby
(“sleep”) mode the device draws very little quiescent current,
typically 0.01µA. The device and PCMCIA port is protected by
current limiting and overtemperature shutdown. Full cross-
conduction lockout protects the system power supply.

Suspend mode is a pseudo power-down mode the MIC2561 automatically allows when V
PP IN
= 0V, V
PP
OUT is deselected, and V
CC
OUT = 3.3V is selected. Under these conditions, the MIC2561 functions in a reduced capacity mode where V
CC
output of 3.3V is allowed,
but at lower current levels (higher switch ON resistance).
