General Description
The MIC2564A is dual-slot PC Card (PCMCIA) and CardBus
power controller. It is a sophisticated power switching matrix
that controls V
CC
and V
PP
voltages to two PC Card slots. The
MIC2564A is used in conjunction with a serial-data output
logic controller using the standard three-wire serial control
data format.
When connected to 3.3V, 5V, and 12V system power sup-
plies, the MIC2564A can switch its V
CC
outputs between 0V,
3.3V, 5.0V, and high-impedance states and V
PP
outputs
between 0V, 3.3V, 5V, 12V, and high-impedance states. The
V
CC
outputs will supply a minimum of 1A current to the socket
and the V
PP
outputs will supply a minimum of 120mA to the
socket. Voltage rise and fall times are well controlled. The
MIC2564A also features an efficient standby (sleep) mode at
0.3
μ
A typical quiescent current.
12V and 5V supplies are not required for MIC2564A opera-
tion making it possible to omit one or both supplies when they
are not needed by the system. An internal charge pump
supplies the internal bias voltages required for high-perfor-
mance switching.
The MIC2564A is protected by overtemperature shutdown,
and protects itself and the system with current limiting and
cross-conduction lockout.
The MIC2564A is available in 24-pin SSOP and 24-pin
TSSOP.
