Overview
MIC94070/71/72/73
High Side Power Switches
General Description
The MIC94070-73 are high-side load switches designed for operation between 1.
7V to 5.
5V.
The devices contain a low on-resistance P-channel MOSFET that supports 1.
2A of continuous current.
The MIC94071 and MIC94073 feature an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state.
MIC94070-71 feature rapid turn on while MIC94072-73 provide a slew rate controlled Soft-Start turn-on of 800µs (typical) to prevent in-rush current from glitching supply rails.
An active pull-down on the enable input keeps MIC94070-73 in a default OFF state until the EN pin is pulled to a hi...
