General Description
The MIC2559 Dual VPP Matrix switches the four voltages required by PCMCIA (Personal Computer Memory Card International Association) card VPP1 and VPP2 Pins. The MIC2559 provides selectable 0V, 3.3V, 5.0V, or 12.0V (± 5%) from the system power supply to VPP1 and VPP2. Output voltage is selected by two digital inputs per VPP pin. Output current ranges up to 120mA. Four output states, VPP, VCC, high impedance, and active logic low are available, and VPP1 www.DataSheet4U.com is independent of VPP2. An auxiliary control input determines whether the high impedance (open) state or low logic state is asserted. In standby mode or full operation, the device draws very little quiescent current, typically less than 1µA. The MIC2559 is available in a 14-pin SOIC.
