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
