MIC2564A
Dual Serial PCMCIA/CardBus Power Controller
General Description
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 and V 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.
• 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 1mA-typical standby power consumption
• Cross-conduction lockout (no switching transients)
• Break-before-make switching
CC

When connected to 3.3V, 5V, and 12V system power supplies,
• 1A minimum V output per slot

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 0.3mA typical
quiescent current.
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
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.
TheMIC2564Aisprotectedbyovertemperatureshutdown,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.

MIC2564A output switches are capable of passing the maxi-
mum current needed by any PC Card. For system and card
protection, output currents are internally limited. For full
system protection, long term (longer than a few milliseconds)
output short circuits invoke overtemperature shutdown, pro-
tecting the MIC2564A, the system power supplies, the card
socket pins, board traces, and the PC Card. Individual
internal status registers for each slot indicate when power
problems exist.
Two flag outputs monitor the V and V output voltages on
CC
PP
both slot A and B, falling low when the voltage is not proper.
Use of these open-drain flag outputs is optional; if they are
used, a pull-up resistor to either the 3.3V or 5V supply is
required. Unused flag outputs may be left open.
PC Card Slot Implementation
The MIC2564A is designed for full compatibility with the
PCMCIA (Personal Computer Memory Card International
Association) PC Card Specification including the CardBus
and Zoom Video (ZV) options.
Control Bus Interface Overview
The MIC2564A power controller communicates with a logic
controller (host adapter) via a 3-wire serial interface. A fourth
control line attaches to the system reset line (RST#) and
places all MIC2564A switches in the high-impedance (off)
state. The reset function is active low.
When a PC card is initially inserted, it should receive V
CC
(3.3V ± 0.3V or 5.0V ±5%). The initial voltage is determined
by a combination of mechanical socket keys and voltage
sensepins. Thecardsendsahandshakingdatastreamtothe
logic controller, which then determines if this card requires
V
and if the card is designed for dual V . If the card is
