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 t...
