Device Overview

Summary

The MIC2568 dual-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 MIC2568 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 250mA for VPP. 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 0.3µA. The power controller includes thermal 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.
