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. The MIC2562A provides power management capability controlled by the PC Card logic controller. Voltage rise and fall times are well controlled. Medium current VPP and high current VCC output switches are self-biasing: no +12V supply is required for 3.3V or 5V output. The MIC2562A is designed for efficient operation. In standby (sleep) mode, the device draws very little quiescent current, typically 0.3µA. The device and PCMCIA port is protected by current limiting and overtemperature shutdown. Full crossconduction lockout protects the system power supply during switching operations. The MIC2562A is an improved version of the MIC2562, offering lower on-resistance and a VCC pull-down clamp in the OFF mode. It is available in a 14-pin (0.150") SOIC, and the -1 logic option is also available in 16-pin TSSOP
