General Description
The MIC2564A is dual-slot PC Card PCMCIA (Personal Computer Memory Card International Association) and CardBus power controller. It is a sophisticated power switching matrix that controls VCC and VPP voltages to two PC Card slots. The MIC2564A is used in conjunction with a serial-data output logic controller using the standard three-wire serial control data format.

Features
• Standard 3-wire serial control data input
• Controls two card slots from one surface mount device
• High-efficiency, low-resistance switches
• 12V supply optional (not required by MIC2564A)
• Current limit and overtemperature shutdown
• Ultra-low 1mA-typical standby power consumption
• Cross-conduction lockout (no switching transients)
• Break-before-make switching
• 1A minimum VCC output per slot
• Independent VCC and VPP voltage output (MIC2564A-1)
• 120mA minimum VPP output current per slot
• Lead-free 24-pin surface-mount TSSOP package
• UL recognized, file #179633

Applications
• PC Card and CardBus power control
• Zoom Video port power control
• Wireless communications
• Bar code data collection systems
• Docking stations (portable and desktop)
• Power supply management
