General Description

MIC2564A
Dual Serial PCMCIA/CardBus Power Controller
Features
The MIC2564A is dual-slot PC Card PCMCIA (Personal Com-
puter Memory Card International Association) 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 supplies,
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

Standard 3-wire serial control data input
Controls two card slots from one surface mount device
High-efficiency, low-resistance switches
12V supply optional (not required by MIC2564A)
Current limit and overtemperature shutdown
Ultra-low 1 m A-typical standby power consumption
Cross-conduction lockout (no switching transients)
Break-before-make switching
1A minimum V CC output per slot
Independent V CC and V PP voltage output (MIC2564A-1)
120mA minimum V PP output current per slot
Lead-free 24-pin surface-mount TSSOP package
UL recognized, file #179633
rise and fall times are well controlled. The MIC2564A also
features an efficient standby (sleep) mode at 0.3 m A typical
quiescent current.
12V and 5V supplies are not required for MIC2564A operation
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-performance switching.
Applications
? PC Card and CardBus power control
? Zoom Video port power control
? Wireless communications
? Bar code data collection systems
? Docking stations (portable and desktop)
? Power supply management
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, 24-pin TSSOP,
and an environmentally friendly (lead-free) 24-pin TSSOP.
