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.
