General Description
The MIC2560 V
CC
and V
PP
Matrix controls PCMCIA (Per-
sonal Computer Memory Card International Association)
memory card power supply pins, both V
CC
and V
PP
. The
MIC2560 switches voltages from the system power supply to
V
CC
and V
PP
. The MIC2560 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 1A for V
CC
and 200mA for V
PP
.
The MIC2560 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 MIC2560 is designed for efficient operation. In standby
(sleep) mode the device draws very little quiescent current,
typically 0.01
μ
A. The device and PCMCIA ports are pro-
tected by current limiting and overtemperature shutdown.
Full cross-conduction lockout protects the system power
supply.
