MIC2564A - Dual Serial PCMCIA/CardBus Power Controller

General Description

The MIC2564A is dual-slot PC Card (PCMCIA) and CardBus power controller.

It is a sophisticated power switching matrix that controls VCC and VPP voltages to two PC Card slots.

Key Features

  • an efficient standby (sleep) mode at 0.3µA typical quiescent current. 12V and 5V supplies are not required for MIC2564A operation making it possible to omit one or both supplies when they are not needed by the system. An internal charge pump supplies the internal bias voltages required for high-performance switching. The MIC2564A is protected by overtemperature shutdown, and protects itself and the system with current limiting and cross-conduction lockout. The MIC2564A is available in 24-pin SSO.

MIC2564A Micrel MIC2564A Dual Serial PCMCIA/CardBus Power Controller Preliminary Information General Description The MIC2564A is dual-slot PC Card (PCMCIA) 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. When connected to 3.3V, 5V, and 12V system power supplies, the MIC2564A can switch its VCC outputs between 0V, 3.3V, 5.0V, and high-impedance states and VPP outputs between 0V, 3.3V, 5V, 12V, and high-impedance states. The VCC outputs will supply a minimum of 1A current to the socket and the VPP outputs will supply a minimum of 120mA to the socket.
