MIC2564A Datasheet (Micrel Semiconductor) - Dual Serial PCMCIA/CardBus Power Controller

MIC2564A, Dual Serial PCMCIA/CardBus Power Controller

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 d

MIC2564A 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-perf
