MIC2558 - PCMCIA Dual Card Socket VPP Switching Matrix

Description

The MIC2558 Dual VPP Matrix switches the four voltages required by PCMCIA (Personal Computer Memory Card International Association) card VPP1 and VPP2 Pins.

The MIC2558 provides selectable 0V, 3.3V, 5.0V, or 12.0V (± 5%) from the system power supply to VPP1 and VPP2.

Features

  • Complete PCMCIA VPP Switch Matrix in a Single IC Dual Matrix allows independent VPP1 and VPP2 Digital Selection of 0V, VCC, VPP, or High Impedance Output No VPPOUT Overshoot or Switching Transients Break-Before-Make Switching Ultra Low Power Consumption 120mA V PP (12V) Output Current Optional Active Source Clamp for Zero Volt Condition 3.3V or 5V Supply Operation 14-Pin SOIC Package Part Number.

MIC2558 Micrel MIC2558 PCMCIA Dual Card Socket VPP Switching Matrix General Description The MIC2558 Dual VPP Matrix switches the four voltages required by PCMCIA (Personal Computer Memory Card International Association) card VPP1 and VPP2 Pins. The MIC2558 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 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.
