... The MIC2560 V and V Matrix controls PCMCIA (Per sonal Computer Memory Card International Association) memory card power supply pins, both V MIC2560 switches voltages from the system power supply to V and V . The MIC2560 switches between the three voltages (OFF, 3.3V and 5.0V) and the V 0V, 3 ...

... Leakage current after 1,000 hours at 125 C may increase up to five times the initial limit. Note 4. Suspend mode is a pseudo-power-down mode the MIC2560 automatically allows when V 3.3V is selected. Under these conditions, the MIC2560 functions in a reduced capacity mode where V lower current levels (higher switch on-resistance). MIC2560 ...

... CC peres, which is far more than the microamperes used by the MIC2560. The charge pump of figure 5 provides this low current, using about 100 A when enabled. When V switch bias provided 12V is selected, however, the on-demand V CC must be used, as this charge pump cannot deliver the current required for Flash memory programming ...
