General Description
The MIC2560 VCC and VPP Matrix controls PCMCIA (Personal Computer Memory Card International Association) memory card power supply pins, both VCC and VPP. The MIC2560 switches voltages from the system power supply to VCC and VPP. The MIC2560 switches between the three VCC voltages (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.
