Quick Detail:
PCMCIA Card Socket VPP Switching Matrix Final Information
Description:
The MIC2557 switches the four voltages required by PCMCIA
(Personal Computer Memory Card International Association)
card VPP Pins. The MIC2557 provides selectable 0V, 3.3V,
5.0V, or 12.0V (±5%) from the system power supply to VPP1
or VPP2. Output voltage is selected by two digital inputs.
Output current ranges up to 120mA. Four control states, VPP,
VCC, high impedance, and active logic low are available. An
auxiliary control input determines whether the high impedance (open) state or low logic state is asserted.
In either quiescent mode or full operation, the device draws
very little current, typically less than 1µA.
The MIC2557 is available in an 8-pin SOIC and an 8-pin plastic DIP.
Applications:
• Complete PCMCIA VPP Switch Matrix in a Single IC
• No External Components Required
• Digital Selection of 0V, VCC, VPP, or High Imped–
ance Output
• No VPP OUT Overshoot or Switching Transients
• Break-Before-Make Switching
• Low Power Consumption
• 120mA VPP (12V) Output Current
• Optional Active Source Clamp for Zero Volt Condition
• 3.3V or 5V Supply Operation
• 8-Pin SOIC Package
