... Latch-Off 5-Pin SOT-23 (M5) Pin Function Supply (Input): +1.8V to +5.5V. Provides power to the output switch and the MIC2090/MIC2091 internal control circuitry. Ground. Enable (Input): Active-high TTL compatible control input. A high signal turns on the internal switch and supplies power to the load. This pin cannot be left floating. ...

... C OUT An output capacitor is required to reduce ringing and voltage sag on the output during a transient condition. A value between 1μF and 10μF is recommended. A 10μF or larger capacitor should be used if the distance between the MIC2090/MIC2091 and the load is greater than three inches. The internal MIC2090/MIC2091 turns off in (typically) 20ns. This ...

... MIC2090 and MIC2091. . OVERTEMP I LIMIT When the MIC2090/MIC2091 is current limiting Eq.2 designed to act as a constant current source to the load. As the load tries to pull more than the maximum current, V OUT increases. When V switch momentarily turns off to insure the internal MOSFET switch is not damaged by a very fast short Eq ...

... Current Limiting for V OUT July 2011 Under-Voltage Lock Out (UVLO) The MIC2090/MIC2091 switches have an Under-Voltage Lock Out (UVLO) feature that will shut down the switch in a reproducible way when the input power supply voltage goes too low. The UVLO circuit disables the output until the supply voltage exceeds the UVLO threshold ...
