MIC2568
Dual-Slot PC Card/CardBus Power Controller
Preliminary
Features
The MIC2568 dual-slot PC Card / CardBus power controller
is a V CC and V PP power switch matrix that supports 3.3V and
5V PC Card (PCMCIA) slot power supply pins.

Complete single-chip dual-slot power switch
No external components required
Output current limit and thermal shutdown
Digital V CC and V PP voltage selection
> 1A V CC output current per slot
> 200mA V PP output current per slot
The MIC2568 can switch PC Card slot V CC voltages between
0V (ground), 3.3V and 5.0V and V PP voltages between 0V
(ground), 3.3V, 5V, or high impedance at output currents of
up to 1A for V CC and 250mA for V PP . The MIC2568 features
well-controlled voltage rise and fall times. Each MIC2568
output voltage is switched by two digital inputs, typically
controlled from a separate PC Card logic controller.
The MIC2568 is designed for efficient operation. In standby
(sleep) mode the device draws very little quiescent current,
typically only 0.3 μ A. The power controller includes thermal
? Ultra-low power consumption
? Compatible with standard PC Card logic controllers
? Break-before-make switching (no transients)

? 28-pin SSO and TSSO package
? Pb-free 28-pin SSO package
? UL recognized, file #179633
Applications
shutdown and protects itself and its PC Card ports with
current limiting. Full cross-conduction lockout protects the
system power supplies.
The MIC2568 is available in 28-pin SSOP and TSSOP
packages.
