MIC2566
Single-Slot PC Card/CardBus Power Controller
Preliminary
General Description
The MIC2566 single-slot PC Card / CardBus power controller is a VCC and VPP power switch matrix that supports 3.
3V and 5V PC Card (PCMCIA) slot power supply pins.
The MIC2566 can switch PC Card slot VCC
voltages between 0V (ground), 3.
3V and 5.
0V and VPP
voltages between 0V (ground), 3.
3V, 5V, or high impedance at output currents of up to 1A for VCC and 200mA for VPP.
The MIC2566 features well-controlled
voltage rise and fall times.
Each MIC2566 output
voltage is switched by two digital inputs, typically controlled from a separate PC Card logic controller.
