General Description

The MIC2562A PCMCIA (Personal Computer Memory Card International Association) and CardBus power controller handles all PC Card slot power supply pins, both VCC and VPP. The MIC2562A switches between the three VCC voltages (0V, 3.3V and 5.0V) and the VPP voltages (OFF, 0V, 3.3V, 5V or 12.0V) required by PC Cards. The MIC2562A switches voltages from the system power supply to VCC and VPP. Output voltage is selected by two digital inputs each and output current ranges up to 1A for VCC and 250mA for VPP.
