The MIC2560 switches voltages from the system power supply to VCC and VPP. The MIC2560 switches between the three VCCvoltages (OFF, 3.3V and 5.0V) and the VPP voltages (OFF, 0V, 3.3V, 5V, or 12.0V) required by PCMCIA cards. Output voltage is selected by two digital inputs for each output and output current ranges up to 1A for VCC and 200mA for VPP.
The MIC2560 provides power management capability under the control of the PC Card controller and features overcurrent and thermal protection of the power outputs, zero current "sleep"mode, suspend mode, low power dynamic mode, and on-off control of the PCMCIA socket power.
The MIC2560 is designed for efficient operation. In standby (sleep) mode the device draws very little quiescent current, typically 0.01. The MIC2560 and PCMCIA ports are protected
by current limiting and overtemperature shutdown. Full cross-conduction lockout protects the system power supply
