MIC2561 Micrel MIC2561 PCMCIA Card Socket V and V Switching Matrix CC PP Final Information General Description Applications The MIC2561 V & V Matrix controls PCMCIA (Personal PCMCIA Power Supply Pin Voltage Switch CC PP Computer Memory Card International Association) memory Data Collection Systems card power supply pins, both V and V . The MIC2561 Machine Control Data Input Systems CC PP switches voltages from the system power supply to V and Wireless Communications CC V . The MIC2561 switches between the three V voltages Bar Code Data Collection Systems PP CC (OFF, 3.3V and 5.0V) and the V voltages (OFF, 0V, 3.3V, Instrumentation Configuration/Datalogging PP 5V, or 12.0V) required by PCMCIA cards. Output voltage is Docking Stations (portable and desktop) selected by two digital inputs for each output and output Power Supply Management current ranges up to 750mA for V and 200mA for V . For Power Analog Switching CC PP higher V output current, please refer to the full-perfor- CC Features mance MIC2560. Complete PCMCIA V and V Switch Matrix in a CC PP The MIC2561 provides power management capability under Single IC the control of the PC Card controller and features overcurrent No External Components Required and thermal protection of the power outputs, zero current Controlled Switching Times sleep mode, suspend mode, low power dynamic mode, and Logic Options for Compatible with Industry Standard ON/OFF control of the PCMCIA socket power. PCMCIA Controllers No Voltage Overshoot or Switching Transients The MIC2561 is designed for efficient operation. In standby Break-Before-Make Switching (sleep) mode the device draws very little quiescent current, Output Current Limit and Over-Temperature Shutdown typically 0.01A. The device and PCMCIA port is protected by Digital Flag for Error Condition Indication current limiting and overtemperature shutdown. Full cross- Ultra Low Power Consumption conduction lockout protects the system power supply.
