Product Summary
The MIC2561-1BM VCC & VPP is a Matrix controls PCMCIA memory card power supply pins, both VCC and VPP. The MIC2561-1BM switches voltages from the system power supply to VCC and VPP. The MIC2561-1BM switches between the three VCC voltages (OFF, 3.3V and 5.0V) and the VPP voltages (OFF, 0V, 3.3V, 5V, or 12.0V) required by PCMCIA cards. Applications are (1)PCMCIA Power Supply Pin Voltage Switch; (2)Data Collection Systems; (3)Machine Control Data Input Systems; (4)Wireless Communications; (5)Bar Code Data Collection Systems; (6)Instrumentation Configuration/Datalogging; (7)Docking Stations (portable and desktop); (8)Power Supply Management; (9)Power Analog Switching.
